It would probably have to be a custom made rig! I've never heard of a tambourine set-up like the one you suggest. I hope you find something! I'm curious to see what you eventually come up with.
I'm a big Stanton Moore fan. If you look under the hi-hat in the photo of my kit, you'll see a Brazilian instrument called a Pandiero. It's a tunable tambourine that can be played with sticks! Mine is a 13" with a calf-skin head tuned just below my 12" rack tom. It sits in a snare stand. I play a ton of New Orleans second-line rhythms on it in combination with the floor tom, rack tom, or snare. The jingles on the Pandiero makes it sound like there is an entire drum corp. coming down the street. Love the sound of it and I find it useful in a lot of situations.
If you haven't experimented with them yet, I recommend to all kit drummers to incorporate a tambourine or Pandiero for a bit. It's not only a ton of fun to play, but the range of new sounds it offers gives new life to old licks and real spice to new tricks. Try one you'll like it! I'm hooked. The Pandiero is now a regular part of my kit and I use it when it's appropriate to the music.

Good luck with your tambourine rig! I'll be watching the thread to see what you turn up!
