Yes (to your post's header question) and no (to your post's content).

 

You can use the same class-map in both IN and OUT CBWFQ policies, as they generally just match packets.  (Although you're not doing so in your posted config, don't forget when matching, and using ACLs, source and destination reverse for IN and OUT.)

 

You can use some of the same policy map class statements, for both IN and OUT, but in your IN policy you're using class statements (queuing) that are limited to just OUT policies.
