Topband: Amplifier Help

[Niko Cimbur]

I first would like to mention that my technical expertise is very limited, and sometimes think I am seeing double.

Can something like this be easily done?  
I am not familiar with the two 750W amps they have, but I just happen to have 
four Intech COM1000 "375W" amps (16 MRF150 in each of them). 
Would it be possible to build a 4 square and feed each element with its own amplifier and switched phase delay?  Would this improve my 160m signal for the next Contest season? 
What if I put it all out here: http://upload.wikimedia.org/wikipedia/en/3/39/Avila_Pier.PNG
