I haven't heard anything about this, but I think it would be a very nice touch to really sell the immersion. If you have VR/Headtracking enabled, or even just using headlook on a monitor, that would drive the animation on your avatar, so that in Multicrew you can see your crew mates looking about. Again, a really small thing, but I think it would do wonders for immersion, and I don't think it would be very difficult to implement from an animation standpoint. Head translation would bring up a few issues, but rotation? Should be easy peasy.
