About the modular approach:
Sorry guys but implementing it like that would leave us with more than a few problems.
1. Basically, everything before the ground-side London scenes is one big video which I cut together. It's one entity and it is almost 100 MB big. Apart from the fact that I'd have to re-cut it for every colour, it would also drastically increase the size of the package.
2. Actually it's not one video but two. Once of them is the citadel opening video (called Cit_Flower by the devs). This video is not linked to any conditionals and therefore will play every time, no matter what. This si the part up to the point where the human destroyer gets shot down so it already contains red ending material.
3. IMO, we'd need a whole munch of new scenes to explain what actually happened. I think you can get away with the destroy ending because here, well, the crucible destroys the reapers and that's it. Simple enough and everyone gets it. Control and syntheses are much more complex and would need some sort of explanation. This would probably mean bringing the catalyst back and I have already overwritten almost all his files to get MEHEM working properly. Hence we'd basically have to start from scratch (and with a more difficult task this time).
So, all these difficulties considered, I am probably going tp pass on that one. However, with a video editing program, it should be an easy task to extract my video, simply cut blue scenes into the parts where there are red ones now and re-insert that. You would however also have to change all the other destroy videos with the control ones. Should be doable without too much effort though, Just extract -> rename -> re-insert (maybe you'll need to change the timing for some of them slightly though).

Since I don't think we know how to add new entries in a sequence, you'd probably have to either "replace" an existing war asset or an edit the sequence to give the new asset.
Sure we do. Changing sequences is what MEHEM is all about. Check out my sequence modding tutorial over in the tutorial section of the ME3Explorer forums. Granted, I only got to write the thing on and off and it's far from finished but I think I can confidently say that I have learned enough by this time to be able to ASSUME FULL CONTROL over a sequence. I can add objects, remove them, change links, transfer objects from one sequence to another, change their linked variables, etc.
I hope that now that I have some time in between v0.3 and v0.4, I get around to update and enhance that tutorial. Right now it doesn't cover more than maybe a fifth of what can be done I am afraid. I am also afraid I am not that great at expressing myself for the purpose of tutorials so it's a bit of heavy reading (in my defense, English isn't my native language

).
About that party:
I have a Shepard standing by at the beginning of ME2 who I want to play through to the end with all the DLC after v0.3 is out (would love to do a whole series playthrough but who has the time). Once I've seen Citadel for myself, we can see what would need to be done and if it's feasible. From what I read here, it sounds possible though and like a good idea at that.
