That isn't practical. You can have other people do the work for the ancestors you've submitted. But, you do have to be a relative to submit a name to have the work done.
I think that people are in fact baptizing whatever names they can get their hands on, in violation of this policy. If it were just peoples' relatives, I don't think there would be an issue here. I would be curious to know who Anne Franks' Mormon relatives are.
