One of my many almost-finished projects…
It's possible, but quite a faff. You need to open up the hole to get the larger bulb in and the reflector material is a high temperature plastic that's loaded with ceramic powder… it destroys ordinary drill bits/hacksaw blades very quickly. I made up a backing plate out of stainless steel sheet for the bulb mount and haven't quite got the positioning perfect yet. It does look as if the beam pattern will be good when I've got it right though.
