No, that's a bad idea.  A current guest would register that as two
disks.  It might even try to write to them independently.

You need an IDE device which can be promoted to virtio at the request
of the guest (so you know the guest understands this type of device).

It would be better if the guest could communicate what it needs.  But
no current guest works that way.
