It's really tricky with GoT, I only had one great RP take off on the old site and since then I have yet to find someone who can take the show but make it their own with me. When it comes to plotting for it, people tend to be a bit difficult since they want to keep political issues in mind and other large scale visions when it can take the fun out of it by over-thinking things. Most fans have been too stuck in a canon mindset to really embrace certain tweaking and changes so I can't say I have any real "ideas" at the moment, my wind has been taken out of my sails lately due to the lack of progress with GoT RPs.

I'm not convinced Tenzin x Lin (prior to season one) needs to end in failure. I'd think the point of doing a RP would be to be able to change events, such as Pema swooping in changing things up. I hated her advice to Korra in season one and how the history was never really explained in much depth so we could do some tweaking there, I've been fairly underwhelmed with development as a whole so I'm happy to do some big changes. 

Yes, you did answer what I was getting at.

In terms of an "AU" or a tweak where a marriage would be given to save Snape, I hadn't thought of that before. Then again, I haven't visited the fanfiction of HP in many years, either way it is a good idea. I had also considered using the Time Turner to sort of act as a tool (if we tweaked it so it was possible to go back as well as forward (rather than reliving the time itself) it could work) for her to visit either of them in the past, say during her sixth year or after the war itself. And we don't need to kill either male either. Sometime simple could be considered, such that say Snape had an antidote on him for such on occasion or Hermione warned him using the Time Turner, and the war was resolved and she went back to school and he went back to teaching. That route would be less hectic but may still require another conflict but I'm just musing aloud here...
