I agree with the comment that this should not be done 'just in case', if there is no "Catalina Smile" there is no reason to sister the bolts.
My C25 has a small crack at the hull/keel join. I call it a "Mona Lisa Catalina Smile".
Ken, maybe I'm not clear. This "inspection" hole would be drilled shoulder to shoulder, so to speak, with an existing bolt but only down to the where the lead starts. I'm not talking about this boring being where I put the additional keel bolts. In this inspection hole I should be able to see a tiny bit of thread and determine if there is any crevice corrosion occuring in the area where the bolt goes through the laminate.
