Definately possible, but not with 2-point tracking only as far as I know.
I saw a video of a buy using 3 IRs on his head (one being further back or forward than the others) to track head motion with more possibilities. Because the 3rd IR is further back, when you turn your head it actually moves left or right while the 2 other points stay fixed, so you get awesome tracking resolution in 3D. Then I did notice that the Wiimote makes a "bigger" point for a "stronger" IR signal, but go figure if it's actually used or implemented anywhere!
Here's the video on youtube

I'm not sure if you wouldn't be better off using an actual Glove like the P5 which GlovePie was originally made to use, though, as IR Tracking is more useful for stuff like headtracking, 6DOF (like the video) and just regular multipoint tracking.
