I'd think Boston has enough concerns with center injuries with Porzingis, so no I don't think theres any way they would want to re-acquire him. Also they are a 2nd apron team so literally cannot trade for Timelord salary unless they trade away one of their players earning more. The only higher salaries they have are starters, Tatum Brown White Holiday Porzingis. So no, zero chance he goes to Boston.
I'd think Timelord is probably the most likely to be traded if he stays healthy though, a nice blend of an inexpensive contract, can fit with any team, and elite play. The only concern is his health, and if he is healthy until the deadline that becomes a risk worth taking for a contender. A highly protected pick sort of like the Josh Hart trade would make sense for both teams.
