I would like to try out the Petrov-Galerkin Enrichment Method (Barrenechea et al 2007) for a mixed-poisson/Darcy equation.Here is the link to the paper:

Basically, this method starts with the P1/P0 combination and enriches both velocity and pressure trial functions with multi-scale functions. Is this easily doable within Firedrake?
Can you say a little more? It looks like I enrich the velocity space with RT0 but somehow only locally (such that I can solve a local H(div) problem to get a correction?), but I don't really know enough about the method to say whether you could do it.
