A couple of others pointed out the common cathode problem to me in direct 
E-Mails as well as the beam forming plates.  As such, back to the original 
push-pull design!

The other problem with it is you can't run the plates in push pull and drive 
the common cathode as it will cancel the output. You would need to run the 
plates in parallel but then there is the problem of the beam forming plates as 
others have mentioned.
