There's an old magazine scan floating around there somewhere advertising a game called "Metal Gear Solid X" which I guess later became MGS2 substance, but it supposedly was MGS2 from the perspective of Solid Snake.
There's some pictures in the scan that show Snake sneaking round the big shell in an olive-drab sneaking suit that... honestly looks like it's made from parts of his Iroquois Pliskin disguise. I saw the scan years ago and the idea stuck with me, so I figured I'd draw a Snake based off of that design. If i can find the scan again I'll post it.
EDIT: just found the scan, lol [link]
