I saw a post a while ago (might have been on BF, but I don't think it was for some reason) that Dexter Ewing had somehow convinced someone at Benchmade to make him a 806D2 AFCK with a Satin blade. It looked really nice.
I have recently sanded the coating off my own 806 and it's not quite as difficult as I expected. I mostly used a Scotchbrite-type wheel on my Dremel and then did a not-that-great job of satin finishing the blade with 320 and then 600 grit wet/dry paper. The nice thing is that if your're careful (I wasn't careful enough, really) you can take off the coating and still leave the logo intact, it goes through the coating into the steel.
Dissasembling the knife really is no problem (though it does void the warranty), and I don't see any 'indicators' that would make it obvious that you had done so (unless you break, mis-assemble or lose parts).
Good Luck,
