Tuning Impact high capacity mag - conversion

[bigHUN]

I have two OEM FX mags for .25 and tinkering converting one to .22. I have no parts in my hands this is a reason to ask...
Is it possible to replace the inner rotating drum only from .25 to .22? What about the hole in housing stays .25?
I am not really interested buying into those 3d filament parts circulating around (I have a LCD resin printer myself and considering those parts superior to filaments)

Anybody can share with me a CAD file (solidworks-solidedge-catia-nx) or a parametric stranslate? for the rotating .22 drum only.

Yes I am in that group but I just don't like FB and the similar social platforms
No worries, I am a CAD designer I can do myself, I just don't know what is a trick with these 3d printed rotary drums vs original - dimensionally...
