You don't have to re-treat the root canal in order to put on a new cap (crown).  But I would seek an opinion from an endodontist (root canal specialist) to see if re-treating the root canal would help.  If the specialist feels that a re-treat isn't necessary, then you can definitely just re-cap the tooth and that should solve the problem as your other dentists have evaluated.  I'm not sure exaclty how a cap can be too heavy though.
