I have some War gear, but keep in mind pretty much everything costs 6k per item to unattune.
I think you might be a little overly defensive on your box setup. You could probably ditch the cleric for a pure DPS. Hell, I was doing PoFire minis with my SK / Shm combo when it was 2 box limit. (You'd need to farm a manastone). I am sure your War, Clr, Shm would do just about anything as long as you don't mind really long fights due to lack of DPS.
