Either go small or play more Gasol and maybe Lee...
This "trap" or hard double on Kawhi on PNR or anytime where he attack is when this team misses Diaw most.
Diaw was a triple threat (Shoot, Drive, Pass) in that position which is mostly 4 on 3 and would take advantage of that all the time. Gasol offers something similar but can't create off the dribble meanwhile Lee can't shoot. Dedmon is in no mans land and LMA will only shoot with no threat to attack etc.
Another option would to go small and maybe play somebody like Anderson etc. just have the ability of triple threat which could make the defense scramble..
But like I said before...Diaw was perfect when it came to teams trying this defense
