Based on another post roughly. Considered a version with Harris going to Portland too. This may not be enough for Dame, but imagine if the Blazers get off to a rough start.

Sixers get CJ to help space and playmake, along with 2 premier defenders (since CJ is not one of those) -Smart - CJ - Thybulle/Covington - Harris - Embiid

Celtics get to make a championship run with Dame and give up lots of young players and picks to do it. -Dame - Brown - Tatum - Horford - Zeller (or someone else at the 3, with Tatum/Horford at the 4/5)

Blazers decide to move their 30+ year olds for youth and picks. In addition to Simmons, a bunch of these guys probably get re-traded, but there is quality in here: Maxey, Pritchard, Williams, etc... -Simmons - Maxey/Pritchard - Powell - Nance - Nurkic
