This is such a good idea. I have the same problem except I have mediums! A while back I had some Japanese sales reps come to the nursery as we stocked their gloves and I suggested they sell a pair and a half of gloves. They though it was an interesting idea. I'm sure that would never happen as they wouldn't sell so many gloves! I sometimes turn a left hand glove inside out and make it into a right hand but it feels a bit wierd. Good luck!
