Would it be possible to build a separate above-ground induction coil that loads a driven ground rod instead of radials?
What about a giant air cap?

Right now, ground radials are not viable for the situation I'm considering.
Ken, if I follow what you propose correctly you are trying to somehow "match" the transmitter ground with the ground stake. A coil won't do this and will work against you. Unlike the antenna circuit, the ground is primarily resistive so there is no capacitance which needs to be negated. A coil in the ground circuit will introduce inductive reactance which will impede the current.

Neil is correct and adding a new component to the system won't help. You might take another look at the antenna pamphlet and check the section on tapping your matching coil.
Using the formulas on Page 5 you can calculate the inductive reactance of your main loading coil and determine the 50 Ohm (or any other impedance you wish) tap. In this way, the impedance of your connection will match your transmitter, improving the performance of the return side.
I have found that connecting the coil this way does improve performance noticeably.
