Pigs are specifically said in the Bible to not chew their cud, so I don’t think that would be allowed for them, but it might potentially work for other animals. I think, though, that the clean/unclean categorization applies to types of animal, not individuals, so even if an individual animal of such a type could be made to chew its cud, it would still be of an unclean kind.
And isn’t there all sorts of disease risk in doing that, anyway?
