The decomposition is possible, but it is possible only if you got uniform scaling. If you got non-uniform scaling you better "bake" the transformations on your editor side, or alternatively bake them during import (i.e. pretransform your vertices). This is for the scene hierarchy of course, since Assimp's animation keys have quaternions. Are you aiming for a quaternion based rendering system ?
