You can do it with overset grids, but IIRC they're more often used
to have two grids that don't conform to each other at all; with
composite elements the research I've seen always had them as
conforming subgrids of the coarse element.

Yes, you've pretty much got to do the integration on the subelements.
We'd have to add a new composite quadrature rule; like I did for the
Cloughs, but more complicated since the FE at each element would have
to supply that element-specific subgrid.
