Letting them in while alive also is harmful because it allows current players to see that we don't really punish former players who used, so there's nothing to stop them as well. We've already seen that both teams and players are not really bothered by the suspensions (Peralta got paid quite handsomely after coming off a 50 game suspension, Melky has done well for himself, Cruz just inked a big deal). So no, keep them out while they are alive. So Ken Caminiti would be eligible, if he was good enough. Hint, he's not.
