Something to do with Sylvanas and a stripper pole in the Stormwind throne room.
...what? Alliance players can dream, can't we?
OK, but seriously, I'd say we'll just ask for reasonable things. For example, we could maybe ask the horde to back out of all the warmongering bullshit Garrosh has been doing. Back off from Ashenvale (while still keeping it contested like before, but without all the horde war machines and military presence there), back off from Gilneas, etc. Maybe give up some supplies and/or labor to help rebuild Theramore, if that's possible.
I really miss Southshore and would like to see the alliance get it back / cleaned up in some form, but I guess we're pretty far beyond any possibility of that now. I actually think it'd be kinda cool if Southshore becomes a proper Forsaken town, but the Alliance gets to retake Tarren Mill. Then it could kinda be like the old days, but with the alliance and horde protecting opposite towns now.
