Sure.

This a Dubro 2.5" spinner, cut to fit an APC 16x6. I had to remove a LOT of plastic. But if you're careful to enlarge the cut-outs equally on both sides, and only remove as much material as necessary, the structural integrrity of the spinner will not be affected.

I used a standard (15mm in diameter) Dremel sanding drum with coarse grit. You'll be there all day if you try to use the smaller one. They only come in two sizes, that I am aware of.
