Well, if you don't mind strap extenders, that would be fine.

I was thinking of how the Stillwater is constructed on that first reverse pleat at the underapron, and how it does not exactly line up with the top apron edge.

If you can not put the kilt on at the last hole of the strap as it is, you are probably going to have quite a wide strip of underapron showing.

That would be the main issue with the extenders.
