If you traded for Trae, what would that look like? Here's one that sort of makes sense for both teams, though I guess all trades like this sort of feel unrealistic until they actually happen.
In the case of bringing in Trae, you absolutely HAVE to move CJ. You can't have CJ and Trae on the same team as they're both horrific on defense. Pels get their distributor/scorer in Trae and they also upgrade their bigs. I can see how BI and CJ could work better with ATL as well. I don't know what ATL does for bigs after losing Cappella and Okongwu, but it's just a random idea anyway...
