We can get knit picky about the amount of picks and where they are going but I think a trade in this format is possible.
Okc takes on Loves cap and sends a pick to move up. They also make the Kemba KP swap, the chances of this happening heavily depend on the Mavs new front office's direction on the KP situation.
Cleveland gets off Loves deal leaving room to pay Allen and maybe sign another FA as well as picking up Bradley who is a very solid backup.
Dallas may be completely uninterested in this deal if their new front office likes KP but if they do a deal in this framework could get done. Oladipo and Holmes are examples of possible FA signings that would fit this new direction of the franchise.
