Electrical transmission poles are, indeed, more cool. So having manual control over them, through use of IE's wiring system, would be great.

Though it'd require duplicate wiring (it also has three tiers of voltage), since there are already conversion blocks and being able to convert MC's power to RF at will, cheaply and without a dedicated converting-place, would defeat the point of having MC's power system in the first place.
Unless it's possible to transmit more than one type of power over same wire without conversion.

Actually nope, same wires, just a second set of connectors. If it's possible at all.
