Interesting idea but I see a durability problem with it. It will not hold up for very long as a trapped raccoon will chew the heck out of that wood and will bend the soft wire and the rat trap trigger bar. May hold a coon but the rat trap spring is weak. It would need to be inspected for damage very carefully after each catch. Take a look at a Lil' Grizz Getter and see how that thing is built like a tank. It needs to be or it will not hold up on a trap line. If you just wanted to mess with making one then I understand that too! Nice job as far as that goes.
Unlike some of the other folks, I do hope you can use it. That is how you will learn what works and what does not.
