   Thanks for all the suggestions on frequency doubling; as usual, I've
   learned quite a bit from all the suggestions.  I guess I should have
   stated the application.  I've assembled a divide-by-three circuit from
   Scott Gravenhorst (thanks, Scott!).  I don't like the fact that it drops
   the tone by over an octave, so I'd like to boost by frequency doubling.
   The circuit puts out square waves with 5 counts high, 1 count low.

It's not at all clear what you want.  Do you want a divide-by-three
circuit with a square wave output?  Or are you unhappy with the fact
that a divide-by-three circuit pulls the pitch down by more than an
octave and you'd really like a divide-by-1.5?

Either of these can be built with a couple of flops and a gate or two
if the input signal is a square wave.
