I don't really know that series, but it was more of a kid's show, right? So there's no way any canon villain would be that evil. If anything, I'd have to go with one of them (like the main antagonist, if there is one. Who would that be?) sending a hitman after Penny after she keeps foiling his plans, would that work? Also 'foot fucking' as in footjob, while she's hanging? (I actually saw a neat picture like that once)

In principle, sure, if I come up with some good ideas. Though I probably won't go with any of the rather messy methods you listed (remember, the whole thing is supposed to be consensual, I highly doubt anyone would pick a method like that), maybe some variant of decapitation, shooting or more asphyxiation.
