The making of kilt jackets in America is an area that could be quite profitable for some one, I suspect, especially argyll ones for daywear. There are quite a few kiltmakers here, but few who make other Scots clothing. I would guess there is an opportunity to get in on the ground floor of a niche market and make it one's own.

I don't know anything about J Higgins' jackets, but have a pair of their diced hose, made from some kind of synthetic material that is not at all of the quality of woolen ones.
