I'm guessing you mean putting a spacer on the face of the bulkhead that bares the thrust of the motor. That would effectively lower the whole retainer assembly. We have about 0.625" of bore on the bulkhead that the motor casing slides into, we could probably reduce that down to as little as 0.2". I think a ring, that sat on the face of the bulkhead, and attached to the top portion would do the trick...
Off the top of my head I can't think of any mechanical problems with this approach. Perhaps that, combined with the countersunk screws, and we could avoid modifying the avionics pieces...
