I think it is ilegal to take wild animals as pets. I suppose it is ilegal for a reason so I would have to say it is not a good idea. If they really want a bunny there are tons in the shelter, maybe you could convince them to adopt one.
If the babies appear to be abondaned I would phone the local Wildlife Conservation and Rehabilitation office.
