To be honest: I have no more insight in these things than you and like you, I donīt know more, as I have read in these threads around here.
Best thing would probably be to start importing a non playable unit as explained by TheDarkWraith in the thread linked above and to ask for help, if a precise problem arises.
Later on, when you are common with the basics, you can estimate by yourself, what it would take to create a playable unit. I have no clue if itīs possible or not.
But hopefully someone else can give you a better answer.
