I don't think it would be terribly hard to customize one.
I've heard the original handle scales can be pried off and that throwing it in boiling water will weaken the glue a little bit. After that, all you'd really need to do is shape some scales out of some material and either epoxy the scales to the liners or drill and tap the liners to fasten the scales with screws. I'm not certain how to go about making the toothpick/tweezer holes though. You'd just have to see how the original scales retain them and carve out a similar hole in the new scales.
Lately I've been brewing a plan to customize an SAK with carbon fiber scales. But the only problem is that I don't have any use for one, since I already have a SOG Powerlock. I'd only be lying to myself if I say I need one for use around sheeple.
