3 x Empire plus Chaze?

So I'm looking to move into an Empire team for a bit of a change. Been getting top 20 with Chaze Wiggs and R2 still but have been gearing Empire of the side. I effectively only have 4 geared Empire and am waiting on Thrawn for 5th.

Would a line up of Ep, Vader, TFP or Tarkin with Chaze work? Or at least for now. Gets the tankiness lacking and off heals too with enough damage.
