This is how I’m currently using the H90. Path 1 is in mono before overdrive effects in front of the amp and path 2 is in stereo after the amp. I would like to be able decide if Path 1 is heard before or after my overdrive section and the RJM PBC10 does not allow for the loops to be reordered. My thought is that this could be achieved by having I/O 1 and 2 on the H90 both sending the same mono signal and I/O 3 and 4 running in stereo. My signal path is below. Hope this helps.
