Just a little suggestion, but once you got the paarthanaax-resolving part down and in the mod (if you don't have it already), why not release the mod as an Alpha then and there?
Might generate more interest in the mod overall, plus there's all sort of paarthanax quest solving mods out already so releasing the mod once that's down (even if that's the only part of it) might help reduce future conflicts.
I've considered that, but there's a lot of other stuff coded into the mod, advanced scripts and the like. I like to build the finale first, sort of- getting all the more advanced stuff like swapping guards over after conquest, fixing the damn Civil War map (while also adding support for flags on your side), making it so you can promote your companions to Jarls (and making it so you can appoint existing power structures- for example, keeping Balgruuf in charge of Whiterun (or putting him back in charge if you'd kicked him out).
Also, my system is there to unlock the new content (which also, for RP content, unlocks the old content). The way I have it set up, you can very easily fail it, and then the only way to resolve the conflict is through killing someone.
Maybe I will, maybe I won't release it. I'd be interested in releasing a showcase, just to show off the promotion systems and such.
