Do you think Chewie will “require” Bossk, Embo, Aurra, or Jango?

In my humble opinion, G11 bounty hunters will probably get it done, if modded well, no matter the hunters. Let's not forget this is a legendary event, and even though it's been said it will be more difficult, they will eventually want to make a mythic version. I can't see there being such a difficult entry requirement to this thing, but I could be wrong.
