Seems like a real waste to cast them off when a simple substitution during assembly would take care of it. Really now, with the attention to such accurate scale detail everywhere on these locomotives, how many buyers of this 'class' of product would ask for the huge coupler on the nose!
Would probably save Scott money in the long run if they didn't even offer the lobster claws. For continuity, both A units as well as the B's should have 'scale' couplers. It is an easy thing to have 'transition' cars (with different couplers on each end) to go in behind the locomotives and match up nicely with the rest of your rolling stock....
