On my RK I combo I run 2 JJ E34L's in the Brit mode of channel two with the gain and trebel all the way up and the other EQ setting to taste and it definitely sounds very Marshall like. I LOVE THE TONE!!!!!!!!! However, I think since the RKII has a revoiced Brit mode I don't think you'll be able to run it with these EQ settings and have a good tone. I tried it with a friends Roadster and it sounded really bad!!!!
