If you can get to FL80 or above could you file an IFR flight plan to join L9 at CPT to KONAN then fit in with Brussels STARS. Obviously might need a bit of orbiting outside of controlled airspace to reach 80 from Popham. If you're aircraft is below 2300kg or whatever the limit is for Euro charges nowadays, and it's de-iced, and you have an IR then why not do that every time, far easier than low level VFR stuff.
