Yep!  I've resorted to doing that in order to fix broken code in short
order (Tux - A Quest for Herring has it for when Tux goes swimming) - but
the precision of roll and heading gets rather poor as you get closer and
closer to 90 - so it has to be done with care.

Quaternions will work better in a space game where there is no inherent
"up" direction...they also handily work around the transition problems
you get with going from -180 to +180 or so.
