Is it possible to have system matrices, dofs and solution vectors etc on two

Since you really only want to interpolate between two meshes, I would just
have two DoFHandlers and two Triangulations and use the class InterGridMap to
translate between the two of them.
Or do you want to say that you want to solve "patch problems" on each coarse
mesh cell? Because in that case, the fine global mesh is not helpful to you
because it only allows solving *global* fine mesh problems.
