Hi zperry94,
Yes, this is possible with the H90. Use Dual routing mode. This way, the H90 behaves like two independent mono or stereo effects processors. On a Program basis, you’ll be able to have one or two algorithms in place of your H9-1 or H9-2, or one effect on each.
To gain a better understanding of dual mode, you may want to study this video: https://youtu.be/0G_WtfUatSc?si=o4chDWbKg1Altt5U
