Being soft copper lines I would go with the repipe method. The flexibility of soft copper might allow for future leaks even if epoxy lining is applied. Keep in mind our ground is prone to movement. Be sure to use Type "K" copper for any underground installation. We use it here in Dana Point Harbor for all reconstruction.
Do you happen to live near a flood control channel with steel sheet piling or maybe a large steel pipeline? These sometime have an Impressed Current Cathodic Protection System which can produce stray currents which will deterioate underground lines.
