Top of windscreen surgery

I have been out in the garage today considering how I will repair the top of the windscreen, where it really needs comprehensive surgery, but where the metal is frighteningly thin. I had thought of reinforcing the area with fillets of plywood inside the frame and fibreglass....but fibreglass and metal is considered a bad compromise as they don't stick very well and are thought to eventually separate.
So Now I am thinking of putting in a steel support and heat-sink.

I think this may be the solution. Rather than remove lots of metal, insert a 2-piece fabricated part from inside the roof. Then drill two lines of holes -along the eyebrow and along the inside edge (see dwg) and spot weld it with mig (not my spot welder, which only works well with virgin steel).

Great to be back at it at last.
