I've said before, and I'll repeat, that her head was intact after what happened. Assuming she's built the way we'd expect, ie, that that's where the brain is, her memories are probably the most easily recoverable thing. The only real question in all of this is whether her Aura is lost, restorable, dormant, or whatever. So I would be a little surprised if we got back a Penny that had no memory of what happened. Seems more likely we'd get a new version of Penny that had some of the same memories.

Regarding magnetic fields, Penny did seem to be clutching at her chest after the wave, before the swords caught up. That would imply she was affected by it. However, the fact that she was coherent enough to notice something wrong also indicates she survived the wave itself, and may well have been ok if she hadn't been caught by the wires.

regarding the cheapness of restoring a killed character; Roman, Amber, and Pyrha are all dead either way, and there's no credible way for them to come back. Because Penny is unique to begin with, reviving her would not actually establish it as possible for anyone else to come back, and wouldn't cheapen any of the other deaths, in my opinion. Furthermore, her death is still going to have a lasting impact. Even assuming her father got the remains imediately after volume 3 and got straight on with the job, it wouldn't make narrative sense for Penny to turn up again before the plot got to Atlas. The length of time in which she is still "dead" and the lingering effects of this would further mitigate the cheapness of her coming back.
