While this might work, or doing nothing to the frame and riding it may work, using epoxy (alone) to repair CF or metal is gonna be pretty useless. The tensile strength of CF is in the carbon fiber, not in the epoxy matrix. CF is way (20-100 times) stronger than epoxy. Same for metal. So to repair a joint in CF or metal that already was too weak to survive, with a far weaker adhesive is probably futile.
