Probably need two antennas, two receivers and a multiplexer that can switch between either receiver as the signal on each antenna fades in and out. It was called "Diversity Reception" and was used for commercial RRTY (among others uses)in order to maintain a constant signal feed to the RTTY machines. The 2 antennas that were typically used were 4 acre Rhombics or similar, so they were spread out over a relatively broad area of land able to react to the ionospheric changes causing the fading. Don't see how you can do it with just two antennas without having them reasonably separated and some way of detecting the change in signal strength to select the appropriate antenna.
Interesting thought however JB
