Richard:

It's unreasonable as a general specification.  It might be achieveable, but it would require special
handling and excessive special processing which is best left undescribed.  Specific designs might work with
this specification, but they should be evaluated by your board fabricator before setting it in stone.

Thie above is just my opinion, but it is based on several years of experience.
