Sure that can be fixed and made stronger but will add some weight.
I haven't riden a fox or dyno but the dyno would have a stronger construction to deal with more jumping.
Suggest routing in 6mm high density pvc foam. Important not to go straight across but angle from centerline to rails from mast track to front foot straps.
Vacuum 'bandaid' foam patch with 4oz wet out underneath. Once cured fair and grind off paint in front and behind to glass in carbon (again patch to overlap foam and cut on angle). The carbon would also lap down the rail crack.
Filler coat, sand, paint.
You would be going really fast and probably legs froze mid air for flat landing, we have all done it!
Need to tuck your knees up, spot you landing and tail first.
Good luck
