OK, that makes more sense, but it would be still no, just not as frighteningly so...
Magnet wire insulation is going to be more fragile and if you're changing
batteries and nick a wire, creating a short would be too easy for my peace of mind. Same with using solid wire, the stranded is stranded for reliability, ruggedness. Solid wire could create a new point of failure if it's anywhere that it would have any sot of mechanical movement or stress.
