Yes, I would, but I'd need to know more about Lopez' health, and I'm not certain how well he fits in Stevens' "system"
Unless we think Memphis is going to be really bad, this is essentially giving up a mid round first + Rozier + filler for Brooke Lopez.
Worst case scenario is that his health declines, and we have dead weight on the books for 1.5 seasons. But, the best case scenario is a pretty good one--he is the best player in the deal, and if he remains healthy he helps us win games. Plain and simple.
