That is not doable for the moment without writing a lot of code a new model of the MeshDomain_3 concept.

Before guiding you to a (complexe) solution, I would like to verify if that worths it. Do you know that the CGAL 3D tetrahedral mesher will remesh your input surfaces? Do you need that intersections curves between the boundaries of A and B are represented accurately in the resulting mesh?
