Tri-lanes don't work as well in League due to the strength of towers and lack of deny. Besides, if you did it, your best bet would be to put it bottom, where there is more room to zone, and you can shut down the AD carry and support.

My team has toyed around with 2 mid, and it can work pretty well, since most AP mids can't hold back a wave without buring all of their mana (don't try vs. Malz) and if you have a high harrass carry champion (Cass, Anivia, Ez) they can zone the enemy away from minions even under tower. Add that the support champ has a bit more freedom in roaming around and you should be able to deny blue buff if you are aggressive. Bottom lane is of course a tanky bruiser with some sustain (Cho, Nasus, Yorick)
