Silent hunter 4 model pack?

Hello, i have looked around facepunch and i have an idea for a model pack that i think could be very popular, does anyone think they could port all the models from silent hunter 4 to gmod?Im thinking all the models (subs, battleships, cruisers, destroyers, aircraft carriers and maybe even some aircraft)

edit:
or could anyone give a link to a tutorial, (and a program i can use to do all this) so i can give it a go myself.
