I don't think there's an easy way via the SDK, but if you can find the
formula for creating a rotation matrix for the axis order you want, then
it's pretty trivial to work backwards from that.
Your idea for using a temporary null isn't a bad one though, since if you
plot the rotation, it'll automatically get rid of any discontinuities for
you (which you'd probably get if you tried calculating it yourself).
