They've shown willingness to go to France before, though. Remember Toulouse's Cup run a few years ago? The BBC chose their match at home to (I think) Widnes over any of the ties involving SL sides.
Also I think I pointed it out in this thread earlier, Catalan v wire was broadcast live by the BBC last year. It would be brilliant if they pick the Catalan game and the Wire game, as then Sky would be expected to pick up the other two and we would get all four games.
