Honestly if you are running 1 war X4 priests, I would spec them all shadow and have VE do all the healing (I believe VE stacks as well).
That works OK up through about the 68ish instances. Once you get to the 70 instances (or heroics) VE is no longer a viable tank healer as it just doesn't do enough. It's great for sustained fights and most trash, though.

I would definitely try that, I dual boxed for long time with Shadow Priest and Warrior and aggro was an issue, so wasn't sure how much worse that would be.
Aggro was an issue because your one shadow priest had all the aggro from whatever you were attacking. Consider that with 4 priests, the aggro is split x4, so the mob will usually die before aggro builds enough to become an issue. Of course, that's all moot if you're spamming mind blast like a crack monkey. :P
