MARC makes a good point as well. On boats I have seen with that type of chainplate (Peterson 34 being one) the attachment point on the hull is either a beam that ties into the keel structure or a fairly large stainless weldment that is incorporated into the hull during layup. Quite often spanning a distance of several feet fore and aft to spread the load. It does have to withstand a few thousand pounds of force. A secondary bond, even if using epoxy and expertly done, would not have the strength of original construction of this type of attachment. And that is why most builders and designers favor the attachment to either the main bulkhead or a secondary bulkhead wherever possible. The cap shroud when heeled in a good breeze exerts a lot of force on any chainplate attachment. If you wish a change best to consult a naval architect to make sure it will work.
