I don't think it would help really. I've done some goofing with soaking, injecting, you name it with a few scents. Didn't see a lick of difference in number of crab in the pot or quality of crab.
If you are looking for a a tip or two here is my "go to tip".
You need bait that is hard to get and bait that is easy to get. GoPro footage shows me that the best numbers of crab that come in and stay in my pots are those that are baited with box or mesh bags of feed as well as free hanging meat that they can really chew on. For example. I like the mesh bags to stuff with fish/chicken, whateve, then I hang either a few flatfish or a turkey leg totally exposed. That combo seems to bring them in and keep them in.
