To answer my own question from earlier in the thread (as to whether or not the Clone Technician is a Hasbro creation or based on conceptual art), the "Making of ROTS" book has a lineup of several Clone Trooper legion designation variations, and sure enough, the Clone Technician is at the far right of the lineup on page 169.
What's also interesting to note is that, of that lineup, Hasbro has seemingly decided to do the final three on the right (Green, Blue Stripe, and Gold) in the final 22. The only other in the lineup that hasn't been made (I don't count those horrid deluxe 3 packs) is the Burgundy Dot Clone Trooper. The other two in the lineup are the 501st Clone and the Saleucami Clone (the Target Exclusive Clone from last summer). I think that, after this at least, the Clone barrel has been scraped as far as it can go.
Which in my mind means that we should/hopefully will get a Commander Neyo, Commander Faie, an SA Commander Bacara, and a corrected Commander Gree in the next few years, should they need new Clones.
