It's probably doable with a little chicanery.  The 765 when 
formatting doesn't actually care what you're putting down in the 
individual sector IDAMs; for the track layout it goes by the 
information in the command.  

One way to accomplish such a format is to lay a track out using 
smaller sectors, say 256 bytes, and specify the needed sector sizes 
in the IDAMs of the sectors that most closely correspond to the 
physical location of the required sectors.  This is what the old IBM 
XDF formatter does.
