I tried what you're talking about with several brackets, but never found anything that worked satisfactorily. My ultimate solution was to toss the RC2's in favor of a PromediaGear Boomerang bracket with their Arca-Swiss compatible L-Bracket. Switching to Arca-Swiss isn't cheap, but IMO it's definitely worth it. I don't use the flash bracket nearly as much as I used to, but I'm still loving the Arca-Swiss quick release system. YMMV.
