Were there polarizers available for TLRs? Wouldn't it be possible to adapt
something similar for an RF?
Maybe for keeping costs down, a double filter adapter could be made that
would just have filter rings so then you could attach any matched (or
mismatched if you wanted to for some unknown reason) pair of filters.
Another thought, could you get a really big step-up ring with a notch
removed for the viewfinder so that you could see the effect.
