Booty you may be on to something there and Like the Captain said spacing between the reflector and director is a matter of frequency not size of elements.

The input impedance may change when the gainmaster gets within .25 wl of another element IE reflector or director, and then a yagi usually has around a 25 ohm input impedance and use a mathing network, gamma, beta or something similar to bring the impedance up to 50 ohm.

Now if you have a GM to play with, try putting a reflector behind it, the boom would need to be isolated from the driven element and most likely the reflector also.

It may be a fun experiment.
