I've got guppies in cold water, and they do fine and breed. They are all the feeder guppy kind though, the fancies are less hardy and really need warmer waters. Where are you? Whether they would die over the winter might depend on where you are.
White cloud mountain minnows are good coldwater fish, they're kind of like coldwater zebra danios.
