Welcome to GT.. You post some good questions and ideas.
If you haven't tried a forum search, you might want to try it.
Go to the main forum page put lefties in the search box... I noticed lefty question post as far back as 2001.
One remark I remember about lefties learning right is that the left hand does the more complex work..
The second thing is the selection of left handed guitars is limited and more expensive.
Would you happen to know the percent of the left hander that play guitar..
Good luck and keep on pickin'
