It would be a pretty slim shim, but is it possible?

I have read on here in the past that some people just tighten them up further and blow the concequenses. However, if you are as OCD about this sort of this as I am I would recommend that you talk to an engineering tool supplier and get a sheet of 0.013" (0.35mm) shim steel sheet.

Yep - USE shim works great. It's a delicate thing though, so take care when fitting it.
