I want to change the hands in a premade puppet. How?

Hello everybody,

I'm using the Mr. Business puppet and I modified it to look like me except the hands. Can I use hands from another puppet and not lose the triggers?

While I'm at it, I'd like my puppet to have clasped hands and cannot figure out how to make the arms and hands do that. The layers prevent both arms from being able to connect in front of the body. Can someone offer assistance?

Here's a look at the puppet and the hands. I had to scale them down in Photoshop because they looked freakishly large. I'm creating a talk show and don't want freakish sized hands on my puppet. lol. Honestly, I'd be really happy with hands /palms facing up, hands clasped, and arms/ hands pointing like the Tull starter and Foxie starter

I attached the Michael puppet if anyone wants to make the change. 

Thanks
