Its been brought up before - and Dan said "not likely" or something to that effect. Some of us were hoping for tan or green handles or blades - but not likely. I know that Dan essentially said "no" to Micarta due to the cost of finishing it.
We can still hope that someday he'll do something different on an LE though!
I would never say never on some options. It all depends on what I can find in the dumpster.
Micarata is still a no due to cost considerations.
