Micro drum kits
Long ago when I did a couple of musical theater gigs, I ended up with a Yamaha hip-gig kit. It's a great kit for portability, but kind of keavy. There's a bunch of innovation lately in small kits that sound good, and are easy to pack and haul. Here's a great example of a small kit with a link to some conversion gear if you're thinking of building your own.
