What you are trying to achieve is a (rather expensive) implementation of a, single, non-steerable, phased array antenna. If there really is no phase difference, you've effectively synthesised a diagonally polarized antenna (although I can't work out why your signal polarisations should only occupy one quadrant). You don't have a diversity system. You could achieve the same effect by summing at the input frequency after a buffer/pre-amplifier.
If you actually summed both with and without a 180 degree shift between the two signals, you could feed them into the main and sub-rx and get true diversity between (for the diagonal case) the + and - 45 degree polarisations. Whether that is any better than true diversity between 0 and 90 degrees, I don't know. Top quoted through policy, not belief.
