Boogered door/fender edges repair?

OP, could you cut that section of metal out, then use the flange tool weld in sheet metal but also ,using benders to go over the edge of the door frame? basically you'd be using sheet metal to make a lower door or corner patch. It would involve drilling the existing spot welds at the door frame i would assume. Hopefully you can picture what I'm typing LOL! but yes id use a flange tool not butt weld etc. also, once down to the door frame you can hammer,dolly and straighten the frame if needed.
