I am afraid that the wall thickness will become too small and the steerer can broke. Is it safe to do that?
Find a shop with a proper crown race milling tool. If you're local to me, I can do the job, but your location is not indicated. Let us know where you are, and maybe someone can make suggestions.
It involves milling the crown race seat, not the steer tube, so there is no danger.
