Well, RA92 is an SDI disk, that is normally located on a UDA50 (Unibus)
or KDA50 (Qbus, as in this case). RD54 is a MFM disk for RQDX controllers.
It's quite different controllers, but the same from a software POV.
An RL11 controller with RL01 disks are something that is 15-20 years
older than RA92 :-)

Besides that, it would work quite well :-)
