I'd just make all of the members of Simulator public. Basically 
everything you do in plugins is in classes that derive from 
SimulatorAccess, so if you do
   const_cast<Simulator<dim>&>(this->get_simulator())
then you have a writable reference to the simulator object and you can 
access all of its member variables (because you've made them public).

Not pretty, but works.

Best
