Here's some bones to a trade that might work. Might need some picks being sent to even out value and I don't like the 4 for 1 with Was.

JB/Burke/TT
Luka/THJ/Green
DFS/Holiday/Iwundu
AG/Powell/JJ
Turner/WCS/Boban
Use JJ's expiring (and maybe one or two of the rookies) to move one or more of Powell, Burke, WCS, Iwundu, Boban to either get an upgrade to DFS (unlikely) or better fitting backups for the PF and PG spots.
