I haven’t read through all the interpretation stuff yet, but I have done a lot of work in the past on quantum properties of radio waves, i.e., photons.
I believe you could build an interference slit which would rotate the polarization of the photon (or part of the photon however you want to think about it) going through one of the slits 90degrees compared to the polarization going through the other. I think you merely need to put what is called quarter-wave plate covering one of the slits and not the other.
BUt I am sure that on the other side of the intereference slit, you will see NO two-slit interference. Indeed, consider the more general case that you rotate the polarization of the photon by phi through one slit vs the other. The amplitude on the other side the slit will be proportional to sin(r) oneslitpattern + cos(r)twoslitpattern which means the intensity will be sin^2(r) oneslitpatteern + cos^2(r)twoslitpattern because orthogonal polarizations to do not at all interfere with each other.
I provide this to help insure your gedanken experiments are realistic before you do too much more gedanking.
