Sure. I already argued elsewhere though that you should only have one
policy for each set of attributes, but if you do in fact have different
attributes then that's perfectly valid.

Not sure whether I think it all that reasonable, since you then burden
userspace with having to know even more intricate detail and not being
able to share code well between commands, but hey :-)
