1. The Kelly flashback was at the bottom of my priorities. :-) I'll get something together. I thought about using the clip from ME2 where Shepard says, "Okay, Kelly" after she tells you to call her Kelly and she gives Shepard a smile.
2. Yes, but standard destroy destroys the geth, so the only two slides were the quarian city, and the Rannoch wasteland. IHJ meant including the geth/quarian peace slide that normally goes with synthesis like MEHEM does.
3. I guess you're confused about synthesis still being available since the MS uses synthesis? That's where the added files come in. I named the MEHEM memorial file "BioD_End002_740MemorialShep.pcc" and placed it in the main game BIOGame folder. Then, running AutoTOC adds that file to the TOC.bin. That file can then be loaded like any other .pcc. So the unaltered BioD_End002_730MemorialGreen.pcc is still present in the EC DLC and can be used for synthesis.
4. And yes, this works for .biks also. The Kelly flashback video is already added as "End03_Flashback_Kelly.bik" but it's just a straight copy of the Joker video right now.
1. That sounds like a good option. Plus, it ensures Kelly looks like her (real) self...imo.
2. Ah, I'm a moron. For some reason this never occurred to me (why the peace slide was missing from Destroy). So...does Synthesis always get the peace slide? Because Shepard could have destroyed the geth back on Rannoch.
3. Ah, got it. Now makes sense, thanks!
4. This is too cool.
5. The Leviathan DLC contains the Catalyst conversation file with some extra dialog. All the lines are from there (the EC version of the convo obviously doesn't include them).
6. No, nothing fancy here. Shep's "The Leviathan..." line is from the Leviathan version of the convo.
7. I originally was going to place it before the epilogue where the Normandy crash was. It seemed better at the end right after Hackett's lines about sacrifices and a future that many will never see.
8. I'll admit, I wasn't certain if I wanted to have the EC Shepard lives music play during the scene. Pre-EC the scene played without music, but it just didn't seem to feel right when I tried that here. And I have one thing I want to try re: the voiceovers before we mix in the audio...
5-6. This also makes much more sense now; I didn't know any of that 
7-8. I'm not sure I know the endings well enough to know what you are referring to here, but my comment regarding the music pertains to how it blends in the vanilla EC as the epilogue transitions through different scenes. It's because the score is continuous. But, that changes as the order of things gets shuffled, so then you have breaks in the continuity of the score, which (to me anyway) is noticeable. Not sure how to fix it, though. You'd have to re-mix it, and possibly add it directly to the biks...or something.
Here is an (almost) complete list of changes. I'm sure I'll leave something out.

Ha! I think I actually caught all of that. And...wow, I'm so pleased to see you integrated ThaneMOD into this. I wasn't sure that was on your list of things to do,! At any rate, a couple questions on that.
Thane LI flashback will show properly with ThaneMOD.
Show proper geth/quarian flash forward slides like MEHEM does and show ThaneMOD slides if applicable.
Does this mean you've actually incorporated new conditionals for both the vanilla one and the new LI one that take into account romance status and whether Thane is alive or not? Since, in theory, Thane can still die in a TM PT, if folks don't have his loyalty or don't save Kahje during Hanar Diplomat?
Obviously, this will be a rare exception, but I just wanted to be sure you knew it was possible. We fudged things a bit with both the EC and MEHEM in that we replaced Thane's vanilla sacrifice FB with the new one. This was in part due to needing the bik slot and wanting to avoid complexities with re-doing conditionals, but also because we pretty much assumed folks wouldn't play to the end of the game if Thane still perished in the coup (rather they would reload their save and fix the problem). If you are fudging it in a similar way, then that's cool, but if you want it to be a simple one-shot install and forget it, then it always has to work, regardless of plot conditions. And...more on this in a bit.
Fob, feel free to chime in if I'm incorrect about any of that, lol.
If Shepard survived, show the MEHEM memorial scene (one with LI and one without just like MEHEM).
Incoming question about this. Have to double check something first. Will edit shortly.
EDIT: Ok, sorry, had to re-watch your MS, and then Game of Thrones was on. BTW, how did I forget how last season ended? Omg. This show is too traumatic for me >.< Worse than Rome, which I stopped watching at the end of the first season.
Anyhoo...
Ok, so to clarify, Shep is in the High EMS Destroy MS, and then, I'm assuming that you are placing the LI in the wall spot for every other ending? Thane, Miranda, Jack, Kelly, whomever?
Finally, a question: how did you edit the dialogue? You know I'm new to this sequence editing thing, so it's just now occuring to me that you can maybe (?) "shuffle/omit" dialogue by altering the sequence links (if I remember right, each line of dialogue is an object in the map). If that's what you did, then that's fantastic as it means no compatibility issues with ThaneMOD proper. But, if you used any TLK edits, that will create compatibility issues with TM. Namely, more TLK variations added onto the 6 that we currently have. I think it will mean 3 more, so we'd have a total of 9. Eek. We should talk more about that on the ThaneMOD forum, if that's the case, ha.
EDIT: The above comment/question is based on my experience with MEHEM, and assumes your edits would be to the main game TLK, and not the EC TLK. If your edits are jsut to the EC TLK, then we're all good.
