Yep, Pjam is really on the mark with detail -- especially with Terminator and Aliens. He's the man! But believe me, I'm as obsessive about detail as anyone here. Just ask Pjam.
It will take some time to find the parts. And it will cost. But hey, you'll have a Goldfinger!
It really gets down to the look you want for him: the gold-lapel tux is fairly simple. A Ken doll tuxedo -- of which there's tons. A little gold paint or material on the lapels. Bam! Auric. Fairly cheap.
As I said, charly_Bond has a suitable Golf outfit and an Auric Stud outfit. Parts can be replaced as better options materialize.
For the Fort Knoex gear -- the uniform, well there's a lot out there. And overcoats as well that just need a dye bath to get that burnt-orange color.
Finding a "heavy" body? Well, the "Goring" figure has a 'fat' body. Or you can just stuff.
Its not really too hard...and its a lot of fun to make your own figure. I've done it alot.
