Sounds great.

That's the first thing I would change. Rigs like the K3S and the top 
stuff have superior strong signal performance and much lower phase 
noise.  You will also want either stubs or high power bandpass filters 
on the output of the power amps on 80, 40, and 20.

I'll let others respond about spacing. For CQP county expeditions, we 
run CW and SSB on the same band with dipoles that are approximately 
inline with each other separated by about 200-250 ft. We run K3s with 
KPA500s (600W). But antenna directivity matters a lot.
