For some morphs it would be kind of  weird for  to change costume; 
PasteUpMorph, BookMorph, PianoKeyboard etc...
I kind of agree that the similarity notion should be all the way down, 
but without some behavior/ editing capabilities default in the system it 
can become a hinder instead of a  steppingstone.
