I can sort of visualize what you are describing. If you were able to post a picture, I bet one of the crafters on this site could make one. I'm guessing it would need really stiff leather to hold its shape. Mernickle makes a 10 shell slide that holds the shells up a little higher, not right in front of the belt, but being a slide it wouldn't work on your gunbelt if the buckle is in front.
