How many degrees of freedom do I possess? Not many. I can think about circuits which defy the conventional wisdom of voltage pulling current rather than pushing current. This makes the Earth a viable source provided your ground is not too close to someone else's, such as: the utility grid.
The following link describes various simulations the last of which (update 26 Dec) is what I am referring to in LTSpice. I apologize for not building these simulations.
Please see attached runtime schematic and graphical result files.
