Ah, so you think he will want to trade CC for something Doflamingo has, huh? Good thinking but I don't think its likely because:

1) Law won't give a f**k at all about that Kinemon's friend to use CC for the trade, its just not significant or important enough a justification for that

2) Knowing that CC is in their hands, Doflamingo will do all it takes to protect the last SAD factory in his island (some SAD remaining is better than no SAD at all) if he knew they are coming to destroy it. With some SAD remaining (in his island's factory) he can still buy some time with Kaido to determine a way out or deal with Law and Luffy to get back CC. But if he lose the remaining SAD which needs some time to reproduce from scratch, Kaido will not like that outcome at all.
