Off the top of my head, you have two options for "hacking" something together. You could put a Really Right Stuff Arca-Swiss compatible lens plate on your 100-400 (part L84) and then screw your Bogen RC2 QR plate in to the auxiliary tripod socket on the RRS plate, and you're set. Or you could use a Kirk SQRC-3157 adapter clamp, a Wimberley or RRS lens plate and the bracket. In this config the lens would mount like any other Arca-Swiss equipped lens/body.
