So, why not leave Rondo and Nelson out of it?
Start with a framework of:
Clippers get KG, Afflalo
Celtics get Caron Butler, Tobias Harris, #2 pick from Orlando
Magic get Bledsoe, Jordan, Celtics 2013 first, two firsts from the Clippers
Add some second round picks to adjust value. ESPN trade machine gives all teams negative wins for this deal.
It breaks down to:
Clippers trade Bledsoe and Butler for Afflalo and a second
Clippers trade Jordan, two firsts, and the Magic second for KG
Celtics trade Jordan, the two firsts from the Clippers, the Magic's second (sending it back to where it came from) and their own pick in 2013 for the #2 pick overall, with Butler and Harris thrown in to balance salaries
I feel like it needs some tweaking and second-round picks may not be enough to get it done, but I think there is a framework there for an interesting deal that is close enough that people might want to play with it and try to add enough to make it seem reasonable.
EDIT: You can also throw in Lee or Terry for Nelson as part of the deal.
