if you run two pieces of coax - maybe RG 58? you will get less capacitive
loss but still get the good insulation - alternatively buy a roll of solid

Coax?

Figure on 30pF of capacitance per foot for coax. It will seriously
reduce AC voltage although with DC you'll get even more spark.

I'm quite sure that stun guns deliver AC, not DC. Frequency would be
in the tens of KHz, nowhere near high enough for skin effect to
operate like it does with TIG HF.

They very probably operate at or quite near the self-resonant
frequency of the secondary, so loading the sec with any significant
capacitance will reduce frequency and peak voltage significantly.
