Specialty wrenches.

I'm in Canada and we've got metric and imperial wrench sets. My boss has issues and does not like imperial. Had anyone ever made a set of metric wrenches on imperial size?

11.13mm for 7/16

12.7mm for 1/2

14.3mm for 9/16

And so on.

I know it's just a novelty but has anyone ever seen something like this or should I just stamp my own?
