Regarding the engineer bit; No, he wasn't a part of the OMNI group. I fact-checked on the Wiki, just to be sure, but the first generation of mobile suits (Strike, Duel, Blitz, etc.) were jointly developed between the Earth Alliance and Morgenroete. He worked on the software for those, before being transferred to the Astrays, which were in part developed from data taken from the G-Project.

As for the photo... I'll take another crack at it, but finding one that fits the general image is a pain. XD
