the power symbol isn't her symbol. Look at the ending of episode 15, when her real symbol actually appears over the credits.

Also, the fact that she uses strings to control her weapons, in a sort of reverse form of puppetry, is about as strong an allusion as anyone has had so far. The things aren't necessarily exactly the same as the originals after all.

To be honest, based on the technology we've seen so far, I'm... not sure whether or not they could have turned Penny into a cyborg.. Certainly her beamblades seemed pretty high tech, but the robots we've seen weren't advanced enough... and it would be really really odd.
