Based on how they play, I actually think Ben Simmons & KAT could be excellent paired up together. Both have very unique skills that allow them to impact the game in a variety of ways, but their skill sets are very complementary. (As long as you can keep their head in the game appropriately).
I like the idea of this trade:

The roster would look like this after the trade:
PG: Scoot, ?????, Johnson
SG: Sharpe, Thybulle, Rupert
SF: Grant, Martin, Jaquez
PF: Simmons, Jovic, Walker, Murray
C: KAT,
Portland would have 2 open roster spots with being ~$10M below the cap. Portland would need a good veteran leadership and a good backup PG & C
Although not everyone on this list is a veteran, these are players that I would target:
+ Xavier Tillman (Memphis)
+ Kelley Olynyk (Utah)
+ Delon Wright (Washington)
+ Danilo Gallinari (Washington)
+ Ish Smith (FA)
+ Matt Dellavedova (FA)
+ Bismack Biyombo
