What about using a through hole jumper to perform the same function as the
zero ohm SMD when the planes are on the surface? Assuming you have some
freedom to place the cross connect anywhere along their boarder you should
be able to find two spots for the through holes. I don't know if that would
change the cost of manufacturing an otherwise all SMD board with only layer
to layer vias, but I would think the process for making a top to bottom via
would also make plated through holes.

  I just know that setting up something I just HAVE to do on the very last
run before submitting is a surefire recipe for disaster for me. I would
rather put up with seeing the short every time I rand DRC than risk sending
the files off to hastily.
