I would produce an aluminum or stainless frame for the Ruger 22/45 but make it as 1911-like as possible. Checkered front strap, beavertail, magwells, and of course any 1911 grip you want to use. I see a few metal options out there but they largely miss the mark and don't have the 1911 in mind at all. I actually can't believe some of the companies went through such the effort and still came out with such abominations. I could buy any 1911 I wanted if I had a million dollars, but I'd rather build what Ruger should have been doing for years.
There are so many beatifully-finished 22/45s out there, but they're all on that same polymer frame even if it has $500 bone grips. SOMEONE MAKE A REAL 22/45 for us 1911 guys. And even the 1911 .22 LR's are painted black without any options. (!)
This is my first post, thanks for reading my BS!!!
