You could start a frontline of
C: Taj
PF: Randle
SF: Morris
Give Portis time at backup to the above.
Get the veteran forwards happy with their roles.
Mitchell and Kevin are less likely to make waves.
Once the larger bodies in the locker room have their pecking order it behooves team chemistry that the backcourt bros find their levels. The Elf-DSjr schizm could rip the team apart. Combined they would make a decent PG, but you can't start both unless you commit RJ and Trier to the pine as bench microwaves.
The "Bench microwave" role suits Trier and RJ at this point in his development but you can't use two microwaves at once ... unless the rest of the three players are basically there for spacing. How would that look?
Well I really doubt it happens but a 2nd unit led by
RJ as the ballhandler
IsoZo as the other G,
with a frontcourt of Ellington*, Knox*, Portis^ would be fun to watch slash rimward and bomb away.
You have the required spacing for the slashers to work.

*such a unit would mean end of bench roles for Dotson and Frank
^I would have liked to put Mitchell here but without a jumpshot to draw away defenders his man would clog the lane on defense.
Dotson, Frank, and Mitch would see smaller roles, as well as Knox from last year. But if you have to piss someone off with minutes it should be the 2nd/3rd year players who get squeezed while you appease the veterans and maintain the locker room.
