Hello,
Insert Loop 2 will need to return to H90 input 4, but that looks like it may be a typo.
Yes, this looks fine. You will have 2 mono insert paths; 1 for your drive pedals and 1 your UA Dream. These can move around in the H90’s signal path by adjusting the insert routing. Then, the H90 will output stereo to the SA Collider, and that will output stereo to your DAW.
