Phyrexian Devourer and Necrotic Ooze would probably be a better way to generate ludicrous amounts of +1/+1 counters quickly. Also works well with Triskelion (so well that people are actually playing that combo in Legacy).
It seems to me that it might be easier to run Steel Overseer, Triskelion and Vigean Graftmage. More straightforward, anyway. All you'd have to do is generate the mana required for the Graftmage; Training Grounds will help, and effectively makes it "U: put a +1/+1 counter on each artifact creature you control".
Pretty close. Since you're running Blue and artifacts, two Silver Myr plus two Myr Galvanizers gives you the infinite Blue mana you'd want for the above, and with all of the artifacts you're running, Grand Architect seems like an obvious choice.
Then have him eat Nicol Bolas and the Magic universe can be awesome again. He takes over the Infinite Consortium and turns it into a trans-multiverse Izzet League. His agents scour the multiverse in Venser's planeships looking for magic to learn, technology to improve upon, and less intelligent people to condescend to.
while this isn't EXACTLY what you are looking for, the closest approximation I could find to what you want is the Graft keyword (that link will take you to all the Green and Blue Creatures with Graft).
I hope that helps you out.
EDIT: Ignore the Burr Grafter however as that got in there by virtue of having it's name in it's rules text for some reason.
