Hi Ted

I understand your question and in theory I can think of no reason why it couldn't work. I know of no kilt makers that use the technique but then I don't pretend to know them all. Having said that - It seems to me the problem is best solved by (a) simply not over-tightening the strap in the first place or better yet (b) getting rid of the third strap - but then I'm a form follows function kind of guy.
