Hmm, I like the intent behind your proposal and as Eppy said, one of the best that has yet been attempted. I personally think you would do better being a part of the QCRF faction just as Unselie suggests, in command of the Cambridge system fleet or something like that.
There are quite a lot of troubles with the Corsairs out in Cambridge, and you can also patrol heavily into Omega 3 (BMM has installations in that system that require protecting). It would give you and the Corsairs something to do involving Bretonia. Additionally, if (or perhaps when), a war between Bretonia and Rheinland starts, you'll be right on the very frontlines, which i'm sure you'll be more than happy to dive straight into and giving it your very best for queen and country;)
These are just ideas and I would not want you to think i'm trying to dictate your roleplay etc, but it would certainly fit in much better and i'm sure you could still have just as much fun. I'm not really sure if there is a niche for a Bretonian intelligence division. Perhaps there is, but I was under the impression that it had already been tried and pretty much failed/died out.
Maybe you'd have better luck and i'm sure people would welcome you to try (if you can get the RP sorted out between all the existing Bretonian factions and yourselves), but i'd like to see you sprucing up Cambridge and giving that area of Bretonia a nice healthy boost. I'm sure you can organise events between yourselves and the OPG there to keep yourselves busy too.
