There is no reason that I know of it wouldn't and couldn't work.  Like others 
have said, many VHF and some HF solid state amps use this method.   You could 
have multiple splitters/combiners for various bands and switch them in/out when 
changing bands (manual or automatic).  As far as using coax for the 
splitters/combiners, that's a lot of coax on 80 meters! 



The other thing though is the power is divided between the two, so if you are 
using a 100 watt exciter, only 50 watts is getting to each amp, I think you 
might need more drive to see any noticeable power increase.   On the other 
hand, at 500 - 600 watts out each, that method would increase the key-down time 
for full duty cycle modes.
