They could be fitted if you wanted to fabricate custom baseplates for them, the Mk6 ones are way smaller in height than the Mk5 versions.When I trial fitted the Mk6 mirror in place there was a half inch gap to the rubber at the base of the glass. I would imagine you'd need to get hold of some 2nd hand Mk5 baseplates and cut them up / blend to the Mk6 item and respray the whole thing.
