or
just get a pro controller, and you have clicky triggers to jump, and an extra button on L to use for shooting.
There are a few reasons why I wouldn't suggest that.
1) it's a circular guard vs an octagonal guard. octagonal is much better in smash 9 times out of 10.
2) you cannot play claw with a pro controller. sure, your intention is to remap jump, but there are plenty of other situations where you have to remap things to make things easier that you can do without remapping just by playing claw.
3) they have a habit of interrupting tournaments. sol has actually had problems with his controller on stream before. some people have even accidentally turned off the console while other players were playing a game trying to turn off the controller. they aren't even legal at all tournaments. so if you have any aspirations of playing competitively I would not get used to a pro controller.
