Yes I've considered pinholes. Mine range from around f/128 to f/180 which in itself reduces the available light considerably.

Which glass on the sensor are you referring to - The hot mirror & AA filter (parts of the sensor stack) have both been removed as part of the conversion of my camera. The Bayer filter & sensor itself will have more glass, that will reduce UV but the thickness of these is minimal (reducing their absorbance) & getting rid of them introduces complications.

It is quite possible that some models of camera will work considerably better than others in this respect.
