My bad - posting too quickly, too late at night. I might have had a martini by then, too!
As I look at it, the capacitor really should go around the resistor and diode, not just the resistor.
Maybe an LM334 would do the job. 40v max; a single 33 ohms resistor will set 2mA, makes a 2-terminal current source - like a depletion-mode FET but with precision current setting.
