Short trem arm for JP15?

I like my trem arms on he shorter side like on old strats or even shorter. For Fenders there are all sorts of custom solutions available.
What about my JP15 seven string? I’m sure I can buy a spare and try to cut and bent myself but then the nice playing is gone etc.
Anyone ever tried that or knows anything that is compatible?
I prefer the arm not protrude over the edge of the body anywhere.
