Then you will have to modify the Fibre Channel dissector so that it has a dissector table that uses the value of fcct.gstype to choose which dissector to call.
At this point, I think one of my biggest mistakes was to give dissector tables names that were the same as the name of the field they used, because that causes a lot of people to think you can use *any* named field as a dissector table. You *can't* do that; registered fields and registered dissector tables are separate, and almost all fields to *not* have a dissector table associated with them (because almost all fields are *not* used in protocol implementations to select which protocol module to hand the packet to).
