Slag, I gotta agree with Russ, that probably wouldn't fly.
Here's an analogous situation: bongs aren't illegal to sell (at least in Oregon) as "tobacco water pipes". Since they can be used to smoke tobacco, they are technically legal.
However, I don't think I'll ever see a "FS: 6-FOOT BONG WITH DEMONIC CLOWN BASE" thread here on AnandTech.
I'd guess anything that treads the border of legality won't be allowed.
