I'll start with the second part. If you are using a block-mapping for
the PowerGridFunctionSpace and a blocked-Vector-backend, you obtain
exactly the decribed scenario. You can have a look at the
pdelab-howto, it contains an example of a turing pattern which does
the same mapping.
For your first question you need to be more specific. I don't quite
understand what you are trying to do there, but I think it might be a
little bit too complicated and yould be obtained easier.
