Omega Music Technology's GM-1 may be the perfect accessory to your expensive hobbies. The system is essentially an intermediary between Guitar Hero or Rock Band gaming drums, allowing you to play along with the games' drum tracks on the real thing ($500 drum set sold separately).
As Ars Technica points out in a recent hands-on with the product, "It's an interesting idea, but you need to be willing to put some serious time and money into the project to get worthwhile results." Aside from owning a set of real drums, you'll need the "fake" ones, too -- the GM-1 sensors send feedback from your drum set to the attached Guitar Hero or Rock Band drums, which then send the in-game cues to the gaming console. Sure, it might work, but who's got the time and money? Oh, that's right, you, Mr. I Own the Biggest Music Game Peripheral Ever. Congratulations.
