If your goal is to avoid relays up in the air, it is easier
if you simply make a 2 element driven array with a phasing
network on the ground.  Two elements, each with its own
feedline.  There are many references describing how to
make the phasing network.

A driven 2 element array will have much better F/B
than you can get with a 2 element Yagi.  The bandwidth
will also be better.
