A: Yes, since the Rule Silver Lining was in play, which says that Creepers don’t prevent victory.

All You Need Is Love requires that you have no other Keepers in play. It does not require that you have no other cards in front of you at all. As long as Silver Lining is nullifying the Creepers win-prevention quality, then their mere presence doesn’t conflict with the win condition described on All You Need Is Love.
