No one can eat a second devil fruit Blackbeard possible can because of his powers or what we don't know yet. Also brook can not because he has no organs to reproduce with. Thirdly why couldn't a devil fruit user have kids I mean it only effects or gives certain powers I don't see how that would effect their certain areas. Though passing down powers seems ridiculous so I hope that puts this to bed.
