Great thinking out of the box. I love avenger style holsters, that's typically all I use. I like the thought of this hybrid, but if I were going to use a pancake holster, I think I might want more substance (leatherwise) around both belt slots. I don't know if I would be comfortable wearing a holster with just a single piece of loose leather supporting the gun on my belt. Maybe, instead of folding the leather over the gun like a traditional avenger, you used 2 pieces of leather to form the holster similar to a pancake, then skive down the portion that would be covered by the flap you have extending. Just to give it a little more material. Or have 2 flaps, 1 on each side that come together and culminate at the belt loop.
