Bump

This is a slightly delayed response, but yes it is possible: I have done it for an Ixon (I also had an Ixon IQ and it's the same for both because they use the same mount).

BBB make a fork mount identical to the B&M one in the photo posted above. Mine's the BBB. Both are much better than the two piece B&M mount which came with my bike but which fell off and smashed my brand new Ixon IQ and which prior to that vibrated all over the place even when strongly tightened.

What I did was remove the small metal dowel that the Ixon clamp hinges on and then removed the clamp itself. What you are left with is an eyelet that screws up to tighten the mount on the fork mount - with the clamp gone it fits fine under the BBB fork mount. I was concerned that the eyelet might rotate through 90 degrees and slip between the gap that's there to allow the mount to be fitted, so I locked it in place with a zip-tie. The mount's been on my bike and used for a daily 20 km commute for a couple of weeks now and there's been no problems and no slippage at all.

It looks like the dowell and clamp can also be refitted to the mount so this mod also has the benefit of being reversable.
