That is an interesting thought... 10kHz is realistic, but there will be
harmonics and whistlers in the arcs as well.  Although the TC isn't
really 
a transmitter at these freqs, it is a near-field interference source.  

Question:  Would a device that produces substantial near-field
interference 
at 9.9kHz require FCC approval?
