interface flux it needs to know few values of the solution in the interior as
well.( I am not sure if it is  an efficient way to compute it in the call
integrate_face_term in the meshworker set up).

I'm not sure whether there is an efficient way for that.

It is uncommon that you would need values from the interior of the cell when you assemble face terms. It means that you have some kind of non-local operator, I suppose. MeshWorker was not written for such cases, so it may or may not be easy to do what you want to do.
