OK. So back to the topic at hand - a system with a hub dynamo driving
a headlight and charging a smart phone and charging a battery - what's
your verdict?

Charging the smartphone could be useful especially if camping, and I'm
pretty sure there are products that already do that.  I doubt charging a
larger internal battery would be worthwhile -- available power is low,
batteries are heavy and lossy.
