"Stare at Catalyst until the crazy stops."
This made me LOL so hard!
Honestly, I could live with this. Even synthesis. I do see a couple tweaks though. I like what you did with the order of synthetics vs. the chaos of organics. They need to reword the catalyst's phrasing to something like that. It can't be "the created will always turn on their creators". And they need to include the other conflicts - krogan vs. turians, etc. - as examples of the chaos of organics. THAT I can buy, I can see that the solution is not about synthetics vs. organics, but of chaos vs. order.
And synthesis is much better done here, but still isn't very clear. I'll have to reread it. The one thing that always bothered me about synthesis is that it, more than any other element of the ending, is true space magic. How does an energy wave generate complex circuitry and organic tissue? I think that, as a more metaphysical synthesis, rather than a true physical transformation, it works much better. Perhaps it is similar to the Asari capability. Imagine if everyone had the ability to understand everyone else. The Synthesis wave could be a momentary joining of everyone in the galaxy similar to that.
I must congratulate you, you've done what I didn't think was possible. You've created an ending that is both functional, keeps with the theme of the rest of the game (with minor alterations), and doesn't change their artistic vision too much. It still requires some changes to the endings, but those changes are hopefully minimal enough that they would be acceptable to BioWare.
My ideal is still something completely different, but since that's not likely to happen, something like this would work.
But they have to keep that line above in. 
Glad you liked it!
I slid a few of those little gems into the expirement, because, well, why not.
As for Synthesis and the technobabble: I tried to write it in such a way that it could be seen two very different ways:
1. It is actually creating a pocket universe with new physical constants, and the Catalyst is controlling those constants as it creates the new world, saving the galaxy by rebirthing it, essentially.
-or-
2. Synthesis does nothing, and saves the galaxy by rebirthing it.
Number two is actually my intent. Synthesis is nothing more (or less) than the result of Shepard's actions being reflected on the Catalyst and
changing it's opinion. It cannot escape it's own programming, "The solution must be applied", so it creates a literal piece of technobabble to rewrite itself into an escape clause, using Shepard's experiences and worldviews to create a new framework for its logic. WIth this new, revised ethical code (including the concept of "strength through diversity", "hope", and "overcoming the impossible", the Catalyst is able to reprogram the Reapers to back the heck off / go away. The "synthesis" is the paradigm shift of a galaxy united to fight the Reapers, then left alive to grow together. It is likely to blur between organic and Synthetic not because "poof", but because it will choose, over time, to blend (like the geth/Quarian resolution of geth in suits). The galaxy is free of the idealogical trap of the Catalyst's logic, the threat of the Reapers, and their own narrow worldview.
Sunshine and rainbows, by way of a slightly-anal/kinda-crazy god-AI trying to escape a programming flaw, and Shepard being willing to go the final distance to free even the Reapers and their master from a cycle that serves no purpose, and degrades every being inside it.
-Just my ideas.
