Well i think you are wanting to tread well into the swamp of Maxwell's equations......Maxwell prooved to us that in fact, in any circuit, the energy propogates as EM waves,........the whole idea of electrons or holes moving about in conductors is just nonsense...but is ok because this "low frequency approximation", to all extents and purposes, works well....even though its a totally incorrect model.
If you can use an incorrect model to design something that works, then you dont care that your modelling was totally nonsense.
