Exactly what I've been exploring using ambisonic recordings from a tetrahedral mic. I've been decoding to fixed HRTFs corresponding to virtual speakers in a cube configuration. Good to know who was doing it and when was already being done. I also made a head-tracking sensor using an accelerometer, gyroscope and magnetometer controlled by an Arduino Pro Mini:
