    Do you have any idea what you are doing? From your post I can't for the life of me figure out what you are asking

    NO DIY here. Call a contractor to supply your needs.

    If you are a contractor, do a proper heat load calc using manual J and then duct design per manual D.

    We can't answer a question like that here.
