I recall Bmi putting an LHR JER service on in the last decade, it was short lived, trying to remember the specific dates, but wad around the time they got involved with BMed. If the bulk of traffic is P2P on GCI route there is no essential need for an LHR link, charges are too high such that will always makes it much more cost effective to fly to LGW.
