Salopian,
That sounds like a great foundation for any numerous patterns and mineral lines. Tiger striping seems a natural for that.
I don't know of anyone in the states who does quality faux stock work but it would be very helpfull especially when lengthening stocks with wood since it is almost impossible to match wood.
It seems to me there would be plenty of people willing to pay $200 for that work and more for a complete stock done that way. Like I said before it would be a nice way to dress up a gun that does not justify a stock replacement or upgrade due to its lower value. There are a lot of fun guns out there that would benefit from this process.
