It will give you a much better choice of mirrors, 10x1.25 mm RHT is the industry norm.
I found a good quality pair of mirrors on Ebay, made for a Kawasaki Z1 - look and perform just like the OEM mirrors on my G/S and GS but cost around $17- each.
I can be described as conservative when it comes to modifications of my bike. So it would seem, even to me, that I should not like this idea. Surprise! I think that's a great idea. Try to remember to tell the next owner if you ever sell this bike.
