How are you going to bond to the steel with epoxy? Obviously it won't bond chemically, you'll only be able to achieve a mechanical bond against however you key the surface. Would it not be better to have a frame builder replace the damaged tubes?
Scotchweld will bold carbon to steel or Al, used it in the Military Aviation world for years.
