Whether or not he can gain significant usage time depends on whether Killua's got good endurance to begin with. If he didn't, then it could be worked on. If he's already above average in that regard, then I don't think it would help terribly much since that means the electrical inefficiency is the dominant factor.
I don't see how he could have a high efficiency yet considering he basically used such grand electric attacks now for the first time. I also doubt he had ever before used his electricity for really extended times under varying combat circumstances. He might have in the past tried how long he could maintain a simple arc, but that's vastly different from what he's doing now. He's not a super uber hyper ant who is born with all the abilities at 100%, so he needs to train for years, just like Netero demonstrated. Nor would his kid's body have as much basic endurance as an adult body (just look at what sort of a hulk his dad is).

Everybody who uses nen for anything concrete is turning their nen into something else. It might be just muscle power like Gon, or something more bizarre like bombs. Turning it into electricity is nothing fancy at all in that sense.
