It is amazing what can be properly repaired from the outside only, but I think when you look at the details of the method you outline, the actual blow-by-blow detail of 'epoxy the new section in place' would be something of a challenge?I know we can’t tell very much from the photos as to the extent of the damage. But I’m not convinced that the internal joinery needs to be removed. … I’m thinking that the keel needs to be removed. The damaged section of the hull needs to be carefully cut out. Carefully shape the edge of the damaged area to a taper … then I think I would make a mould suitable to layup a replacement section for the damaged area. Fabricate the replacement hull section to fit exactly. Epoxy the new section in place. Re attach the keel … now I’m aware I am not a shipwright. But I can’t see why that wouldn’t be a good repair if done very accurately and carefully.
And 'make a mould' is not trivial either, but repairs have been done that way, sometimes using a sister ship to take a mould from.
As a DIY prospect, personally I'd say my skills would be plenty adequate to repair it mostly working from the inside, ypur method would be beyond me for something structural to the point of the keel hanging on it. I've repaired impact damage to a Laser from the outside only, let's just say it's easy for things to not follow the textbook quite as closely as one might have hoped.
