Would it work to replace the focusing screen with a uv filter sanded with high grit sandpaper?

Sure, but that wouldn't be an adapter with NO focusing screen, that would be an adapter with a focusing screen made out of a UV filter. You can also make one with tracing paper or waxed paper as a focusing screen. Any of those options will result in varying levels of quality.

An adapter with NO focusing screen would be one that simply focuses on an aerial image. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
