See this, here, is why I don't think Penny got given her aura from another person. There's no indication that she has any emotional baggage from any previous incarnations, and she certainly doesn't act like she has memories of being human.

On the flipside, such things were a very real concern with using the aura transfer machine, so clearly they hadn't ruled out that it could happen. And then more recently Ozpin's aura is somehow transfered to Oscar, and this literally manifests Proffesor Ozpin, personality, memories, and all, as a voice in Oscar's head.

Although regarding develloping aura, we know it regenerates with time, and isn't somehow essential for a person to be functional; Mercury broke his and didn't go into a Coma. And of course there's the complete nonchalence people have about damaging it when it's above 10% or so.
