Create multiple OSDs per disk? Nowadays (luminous) this should be possible by creating multiple LVM volumes (filestore), or by creating different mounts and use filestore OSDs and or creating different parititions and put bluestore on top (if you need to test bluestore as well). Forcing CRUSH to do things it shouldn't will be much harder I guess / hope ;-)). Gr.
