I know Demar DeRozan doesn't shoot 3s, but I might consider a deal based around Conley for DeRozan. As a 2nd or 3rd option playing on a spaced floor, he might work. He'd at least give the Jazz a little more size and rebounding compared to Conley.
Starting five would then be Mitchell/DeRozan/Ingles/Bogdanovic/Gobert. That's three 20+ ppg scorers on the floor with Ingles and Gobert. DeRozan coming downhill off Gobert screens would be a weapon. He can also pass a bit. That ought to be enough to take out Houston.
