I've never done a kydex x-loop because it's easier to just turn a Tek-Lok or Kydex loop into a new position instead, but I'm sure it could be tried. Send me a PM or email if you want and I'll be glad to help you figure something out.

Here's a couple of Drop loop sheaths.





Something like this with an x-loop, or a couple of x-loops would be handy.
