As far as I am aware, the qhy9 has these specs

body to sensor 15mm
optic window 12mm
FW 18mm

With threads and the 5 mm adaptor for the filter wheel to mpcc I get 55 mm to the shoulder of the mpcc.

you have a say 10mm OAG in the system, so I would have thought that taking the 12mm optic window out would pretty much get you dead on the mpcc specs.
