When I killed Bloodqueen 10 yesterday as offtank, I freaked out when she suddenly ran away to bite, forgetting that it was the bite and not the MT that lost aggro. As a result, I taunted, and she redirected from the mage she was supposed to bite, and bit me instead.
Clearer:
1: Lanathel picks a bite target
2: She jumps
3: You taunt her, while she's midair.
4: Profit, by getting 100% damage buff first.
Remember that your guild might not like this, but also, if you are a high dps and are supposed to be the first bite target, you can do this.
UPDATE.
Someone have confirmed this:
(Reason to bad quality is paint. I can mail you a better quality picture if you believe it's photoshopped and blurry due to that).
This means you just have to be lucky with the time you taunt on, and your MT will probably have to taunt back.
