In reply to my own question (for the sake of future generations of desperate newbies ;)
Operations like overlap integrals between field profiles defined on different boundaries seem to be most easily done using component coupling operators, e.g. linear extrusion. In this way you can map a quantity defined on one boundary onto the other boundary, thus making them both available for calculations on a single boundary.
Good luck!
