Worked very well with a similar item: Haris Pilton's Gigantique Sack until it was hot-fixed.
Advertise in trade on a scammed account:
"Buying mechano-hog cheeve, 500g"
People will whisper you laughing, calling you a scammer, but occasionally you will get the few hopeful people trying to earn their money back from attempting to invest in one themselves.
If they ask you details about it simply state
"Once you trade it, just like once the engineer crafts it, I gain credit upon it entering my bags. Once that is done, I trade it back and the deal is over

"
If they ask why its worth so much to you, your'e simply trying to get as many achievement points as possible, as you have cleared most content and finding yourself bored.
Currently working on this now. As the price for hogs averages 15k, you will have trouble finding sellers rather quickly, but the turn outs will be huge.
You MUST have gold to invest in this, but expect your investment to turn over ten-fold.
A level 80 toon is highly advised. The more experienced and already aged scammers will find this easier, as they have higher funds and numerous scammed accounts to work on.
Quick, easy, painless.
And again, for what its worth, give it a shot. Worst that can happen is you get laughed at.
