Of course it is fixable, anything is fixable if you throw enough money and parts at it. "I have my Grandfather's Axe, my Dad replaced the haft and I replaced the head. I have my Grandfather's Axe."
My 24-105L f/4 does the same thing, I just live with it. The images it produces are still just as good.
The problem with the 'flopping' aspect of this lens and all the Canon zoom lenses with this poor design is the risk of breakage internally, a failure the original 24-105L is particularly well known to encounter. I've used the LensBand on a few Canon zooms. Careful placement of the band position and it becomes less annoying, until you replace the lens with one that includes a lock.
