Depends on if the dirven elements are at the same 
place on the boom.  If they are in very diffrent places on the boom
then the antennas will not be in phase and this might 
cause some problems when they are both pointed the 
same direction.  K8CC did some modeling - and wrote it 
up it the NCJ a few years ago - about what can happen when 
you stack a 3 ele yagi with like a 6 elel yagi.
