Liquid Ocelot is not actually Liquid but self-hypnosis that Ocelot did to himself to trick the patriots. So no, he never would. Liquid on the other hand would have rapid aging once he reached of age like Solid did had he not died. It was a fail safe for Zero's/Chiper's Les Enfants Terribles project. Solidus Snake is different because he was engineered to age faster and basically was an adult within weeks instead of being a child. He was also more or less born from a test tube where as Solid and Liquid were embryos that Eva actually carried within her.
BTW both Resident Evil and Metal Gear Solid are my top two favorite video games. How ironic, then again if you like one of the two games then you are most likely going to love the other. They tend to appeal to the same crowd even though they are vastly different, they have a similar feel to the games and the complexity of the story.
