If I didn't know how electricity works well enough I would have been tempted, but it's not really possible from any feasible standpoint to do FMA alchemy with electricity by manipulating electrons and such. To get a lightning bolt in an inch of air you need 50,000 volts to travel the gap. And that's for every inch! Without coils on hand to make a transformer and such alchemy can't really solve that issue. I think I might go with some kind of metal, Carbon, or just gotta think more.
