There's no need for this thread, for a couple of reasons. For one, though the last war did have moments of plot changes on the fly (the Forum wars being a great example of that), the vast majority of it went as plotted and scheduled out ahead of time. Everything that would happen or did happen, was mapped out by the creators and the artists that were involved in the crossovers. Pulling random ideas out of yet another "what if" thread would only make things that much more convoluted.
For two, there's literally ZERO plans for another war right now. It's great to be enthusiastic, but you can't force something to happen that's just not possible at the moment. Sorry!
