Hi Matt, they already have its called the US147, I sail it regulary with an 8.6, unless it is really choppy it wont be too comfortable but it can be done, as soon as you are always powered on the 8.6 you can pop it on your is110 like I do.
I was trying to make some of the points that Sean made earlier, it could and will become a heavy sailor only competition and do competitiors really want the hassle of lugging around a formula board and 12m sails, trying to get them on aircraft, I had trouble just taking an 8.6 abroad once!
At the end of the day it is up to the current crop of sailors to vote on this which may be sooner if there are any more light wind events!
