Glad to see that you have all the "answers" :-)   How is that bottom line 
going to drop?
Using SSB vs. AM analogy is way out. We are not talking here about resistance 
to new things, we are talking huge advantages that only stubborn could not 
see: 1/2 or less of the signal bandwidth, 1/4 of power required for the same 
signal level, no huge modulators, transformers and duty cycle. See the difference 
between BC610 and TT Titan kW rigs? The bottom line is 20% of cost and 4x 
signal advantage. If you can achieve similar feat, then you got a winner. Talk is 
cheap, results speak for themselves.

Some serious people were playing with antennas and radios for over some 100 
years, antennas been around, amplifiers been around, your proposed solution did 
not emerge as a winner (there are some applications, where justified, but at 
a cost). As I mentioned, the reasons I see are: intermods in amp/ant modules, 
TX vs. RX, complexity and cost. Do I want to pay more to get the same or less? 
Not yet.

What we have now is better modeling and analysis of arrays and software 
simulation, optimizing arrays for best TX and RX performance, better fitting of 
arrays for propagation modes and flexibility to adapt. For those willing to 
travel, taking advantage of geographical features to enhance performance of 
antennas gives another benefit.

73 & GL!
