Unusual H90 setup, can this work?

[Talesmusic]

I thought this would work, but I'm doing something wrong, apparently. I try to set up my H90 so I can use one patch before my drives and one at the end of my chain. I also want to send the 'out 1-4' straight to the H90, so I bypass my drives for one amp that has natural overdrive. Can somebody point me in the right direction?

It looks like It is not possible to have 2 mono-ins and one stereo-in in the H90, so I guess it is not possible
