Look I will be the first guy to say that anything can be repaired but there is a point where some things shouldn't be repaired , I believe you have reached that point.
These Metton hulls have some weird stress characteristics , I say this after repairing tons of them over the years , I have seen skis hit in one area and stress crack on the other end of the ski , also the green glue that bond the hulls together has two weaknesses , heat and impact are the only two things that affect it , it is very possible somewhere else on the ski the glue has popped loose or separated , quite possibly at the bulkhead given the impact area on this one, the real issue is you probably won't find it till the ski is repaired and dropped back in the water at which point it is too late..
My best suggestion to you and I am sure some others here will say the same thing is to find another hull and swap out your parts, in the end you will have a better, safer hull and it will most likely cost less money , I know for a fact it will cost you less ski downtime.
From what I am seeing here you would need at least gallon of epoxy resin, yards of biax fiberglass cloth , two part urethane foam , cabosil and fairing compound , primer, paint , graphics , contact cement and hydroturf , mixing containers, paint brushes , fiberglass rollers , mixing sticks and there are probably a few more incidentals I am overlooking just to get you back to where you were before the madness happened.
If do you insist to persist in this venture follow the linky thiny , they have everything you need except primer , paint, contact cement and turf.
