Adding a Qbus to it would certainly offload the work of implementing
storage - just put it on the user to find a Qbus SCSI card or a KDA-50
or a Qbone or whatever and you wouldn't have to worry about OS drivers
or (alternately) mimicking a vintage disk controller.

I would hope it would use its own RAM.  No point in forcing anyone to
use vintage RAM.

For convenience, it would be nicer to have some sort non-spinning disk
rather than a $$$ vintage controller.
