You can live bait by trapping an animal and then surround the trap with traps targeted at your desired target, but that won't allow you to move the lures, though, nor keep them alive for an extended period of time.
Similarly, you can tie domestic animals to trees as bait and use fences and traps around the bait animals, so bear/wolf lures are already available (and they don't even die of hunger/trap injury/shock...). Note that you should take measures to avoid the predators passing through/over the fence...
