Pelicans: Acquire James Harden who they would like to pair up with Ingram to be an unstoppable scoring threat. They have good defensive guards like Alvarado and Herb, so they should also be fine with trading an offensive player in McCollum for another in Harden which is a major upgrade in my eyes.
76ers: Acquire a very deep bench with McCollum, Boucher, Richardson, and Otto Porter for Harden and low minute players. In my opinion McCollum is probably the best possible replacement for Harden to pair with Embiid, and acquiring a deep bench should help their weaknesses a lot.
Raptors: Break the team apart after Vanfleet leaves for Houston; Make the team younger and build around Scottie Barnes by obtaining FRPS from other teams by trading older guys.
