Jaylen Brown trade

Is it possible that the Celtics make a trade for Jaylen Brown that makes them less of a contender this upcoming season? For instance, if they were to accept a package of multiple first round picks for JB. Or a mid level player and picks (a move that would obviously make them worse this season). Now that Giannis is out, I’m having difficulty finding another player they could trade for that would make the team better compared to keeping JB.
