I could do what you're talking about, I considered it once upon a time with a slide safety Jericho. The Tanfo would be a pretty straight forward conversion, but even if you pulled it off, the resultant abortion would be worthless to anyone but you. If you want to do it for the hell of it, just to see if you can, I'd be happy to provide ideas and dimentions, but it would be much more cost effective/simpler to get a frame safety gun to start.
