New to Multi-boxing (2). Need someones opinion.

Hey guys. So last night I finally got keyclone and set everything up. Earlier tonight I started my first dual boxing team of a troll Shaman and a troll Mage. Will this work out? I was thinking Of going ele on the shammy and fire on the mage.That way, they will both be great casting DPS and will have good support with the shaman. I plan on trying 5 boxing whenever I get the money. What other classes could I add to this setup to be able to effectively do instances and Pvp? I have seen Fi,Fye,Fo,Fum in a few BGs on my 70 druid. I know he does all shaman...but could it work with different classes?

Please answer any of these questions and give me any other information you think would be helpful to a new multi-boxer! :D
