I was thinking about this last night when I set my phone down on my wireless charging pad. I'm curious to see how long it takes for it to be implemented into mods. We already have voice control and touch screens and speakers in them now. Or will samsung come out with a Galaxy with a 510 on top of it. Maybe smok will start making phones next. It seems like a silly idea, but Chinese companies are sure heading in that direction in my opinion.
Not viable especially for bigger batteries. IF they do try it the mod would heat up also the batteries would heat up which is not good. Also it would be too slow of a charge. Thirdly most mods do a poor job at balance charging as it is.
