Ah, I see what you're asking now. I was over-idealizing (I believe my answer is correct if you assume no slippage and no deformation). In the real world, rolling friction will likely be less than static friction. But it's non-trivial, and you haven't given enough information to answer the...

Take one equation, solve for Fr, plug it into the other. (Note: I didn't check your work for errors). No. Have you ever seen a screw without threads? Yes, the "squeezing force" will try to push the taper roll upwards, but that's due to geometry, and should be covered by the static equations...
