is there a mod so i can use the cymbals from rb2 to work on my ghwt set?

my yellow cymbal wont work on ghwt i can plug the orange up on the yellow side and it works but the yellow will not work on either,was wondering if there was a way to mod my ghwt to use the cymbal kit from the rb2 kit,ghwt has a mono plug for its cymbals but rb2 has a double jack.thx guys
