Where does Ben Simmons go next?

[thejazzcollector]

So I've seen some takes on this board that Ben Simmons will be riding the pine within a few years, others from the Philly faithful who are defending him and compare him to Giannis, and of course the notorious 76ers fanatic who now seems to be avoiding BO altogether after talking a lot of smack the last few weeks...
Nonetheless, after Embiid and Doc Rivers' comments yesterday, it seems like Simmons could be on his way out, although given his contract it won't be easy to move him.
Curious what everyone's thoughts and genuine feedback are on this trade I conjured up in my head today, or what other possible scenarios are out there.

Mavs get: Ben Simmons
Thunder get: Kristaps Porzingis, 76ers 1st, Mavs 1st
76ers get: Kemba Walker, Mavs 2nd

Swap a bunch of underperforming players on bad contracts for one another. Luka can play off-ball a little more but he’s still the ball handler down the stretch. Simmons can focus more on defense and facilitating for the bench. Dallas can still space the offense by playing Kleber at the 5.
76ers stay contenders and get a point guard who can actually play at the end of games.
Thunder get more picks because Sam Presti loves them and they hope Porzingis returns to NY form.
