Can one use 1.8 mm bars with wider end pins?

The crown on V2 looks sharper to my eye. Yuki told me this week that the max bar width is 1.8 mm. What problem would a 1.8 mm bar present in the 2 mm hole of a 5512? Would the slightly thinner bar actually work okay? Would it damage the 5512? If a 1.8 mm spring bar would work okay on a 5512, I'll get one of these bracelets.
