    Or maybe cut out the wooden frame, make a temporary form attached around the opening, and wrap the opening with glass unis?

    If you had a separate piece, that covered the region you show in that image, is the way to go.
    As also noted, make a template from the window. Make the wooden insert very smooth from one piece of wood that extends over the region you indiacted, not joined or scrafed. Make sure the radius is very smooth with no score marks.

    Not a great idea IMHO. You are just introducing another interface that will have to tied into the boat.
    The other corners are not cracked so build up the cracked frame by running 2 inch FG biaxial strip around the inner/outer edge and then heavy biaxial flat on both sides of the opening; up to the roof on the top, to the door frame on the inner side, to side wall and say 6 inch at the bottom.
    Use just the FG/epoxy. its good enough.
