Why not just go with your gut and write what you think? While it's sweet that you want to fix the storylines in a way that's pleasing to as many people as possible, I think most people would be more interested in a deeply felt narrative that you really buy. Writing by committee isn't likely to produce the kind of work that inspires deep passions.

Just my two cents. I really admire you dedication and your efforts to make the MU a little brighter. :)
