For god's sake. These theories are so ridiculous.

The first twin clones (Solid and Liquid) were born in 1972. Solidus came sometime later (though when exactly is not clear)

His accelerated aging allowed him to appear in his late thirties / early forties when he was only about mid twenties. There is no physical way for a child to be accelerated in aging to appear to be a man. Solidus would be three at the oldest by Ground Zeroes (that's if he was born in '72, shortly after the first clones) and it would not be possible for him to keep watch for someone over 9 years.
