I like the idea of Phalanx. I think Taevon, with his distrust of, yet singular reliance on technology will provide some very interesting tension between the two. Plus, Legion was one of my favorite squadmates, possibly my #1, and I would love to see another rendition of a Geth unit. Just a tip, though, Geth have little to no individuality. Legion was named such for the Biblical demon, Legion, who was not a single entity, but a thousand, a "legion" of entities all rolled up into one. So, more than anything, a Geth would be a link to a whole, rather than a single person. Just my two cents, but as I don't fully understand the Geth collective after leaving Reaper control, Phalanx could be totally alright. 

I also love your choice of the name Phalanx. Did you choose it for its inability to be breached easily, or its anticavalry capability?
