BaronG just gave the most valuable piece of advice/information I have seen in a while on this sub-forum. Seconding his thoughts, I would add:
a) Get a JAA Class 1 Medical - Has done be done in Gatwick if you are doing with the UK CAA which you should. Any other National Aviation Authority will require the same and won't have FTOs out of Europe. Later on you can conduct your Medical renewals in Ormond Beach, FL.
b) Just do it through Bristol, ideally you would sit your exams in Lakeland, FL and do the flying portion for the CPL at Bristow in Titusville, FL. Since you do have 76 time you should know that FlightSafety Int'l in West Palm is a UK CAA certified FTO, you can definitely arrange a checkride there in order to have the SK76 type on your JAR license.
c) Download the LASORs from the UK CAA website and start getting acquainted with it!
Or ultimately as it has been suggested just replace wives
