The first hack that jumps out at me is a physical wire and two access
ports.  It¹s ugly but you should be able to do it.  Of course, you¹d have
to have a separate setup for each vlan.  Are the conflicts in the middle
or on the end?  Could you double tag them and then strip the outer tags at
the customer handoff?
