What about this scenario from the Clips perspective:
Trade Griffin, Bledsoe, Butler, Jordan -- Salary Out = about 38M
For Pierce,KG and Bass -- Salary In = about 34M
Amnesty Pierce (if this is possible -- not sure of the amnesty rules) or release him owing the 5M guaranteed.
This reduces their cap to about 30M. If the cap next season is 60M that leaves 30M to sign CP3 and Dwight Howard (this assumes that you can't go over the cap to sign CP3 with Bird rights and that you can only get 10M of PP's 15M off the the books).

Now there's 20 minutes I'll never have back.
