Best rebel team for Tank Raid?

So I wanna put together a good rebel team specifically for the non pvp aspects of the game, I've pretty much got the gear for Wedge and Biggs set aside, I just need a few Stun Cuffs and to star up Wedge, but I don't really know what to do for the other 3 slots, I could bring R2, but I feel like he's better off with my Jedi
This is what I've got to work with, I might just gear up Han since he's an easy 7*
