The aforementioned video
I'm also obviously far from an expert, but I had a couple thoughts. First off, I think that a Stetsbar might be a better option. If it's got to be a Kahler I think that I'd want to either do f-holes, or a soundhole moved to the side, so that I could do parallel bracing & run it under the mounting of the kahler. There're a lot of other options too if you're willing to do it less like you would on an electric, then you could extend the tail block & mount it strait to the block (through the top, remove the saddles, & put on an archtop roller bridge, like you would with a Bigsby.
On a lighter note, have you talked to Gary Kahler? I know that Neal's close with him, maybe he can put you in touch, & who knows, maybe he's got some ideas floating around.
