We would absolutely love to do this in the future. Our main concern is that since we're a smaller exchange, it would make matching a lot more difficult since the pool of writers/recipients is smaller than other exchanges, but the diversity of the interests/requests might be too big. We're certainly always taking it in to consideration, and perhaps if we're blessed with more time to plan (this year has been hectic for all of us) next year, we can test it and see how it goes.
