The best way to do this from drum set point of view would be to use samples.
A set of Concert Chimes can be quite expensive, especially one that is in tune. You might be able to find an old one that a school or an orchestra is selling. However, lugging one of those around is not fun, and they generally aren't built for travelling. They are struck at the top of each tube with a large hammer shaped mallet made out of either some form of epoxy, or rawhide.

Of course...if you have someone to lug all your stuff around, and money to burn...the more toys, the merrier!
