Yes I understand the null zone, but my comment was based on my situation. I have a similar 90 degree apart transmitter issue and was able to tune in both directions by aiming my 4 bay about 20 degrees away from one tower direction.

The 90 degree off tower cluster is much closer and more LOS to me so being further out of the main beam path was somewhat compensated by the stronger signal arriving at my antenna. At least enough to allow me to tune in those channels. (Well other than the tree problem, but that's another issue.)

The main direction is further away and 2edge, but even with my antenna aimed 20 degrees away the signal quality is still quite good. I only have very occasional weather related problems with the one VHF-HI channel from that direction.

PS. My 4 bay is a DIY based on Mclapp's 10 x 9.5, no reflector.
