I know of one USA owner who is in the process of doing this and one of our European forum members is also doing this modification. I am not aware of anyone who has fully completed this modification.
It will of course require a custom glass which is obviously an expensive process. I believe it will also require reworking of the doors to allow for the expanded U-channel and felt whiskers to be installed.
Certainly not a weekend job and likely several months minimum required to just get the custom glass
IMHO this is a major process, likely not reversible, and not worth the effort
