One thing I can't tell is if you set like guaranteed-bandwidth in a shaper with those regulating policies while other policies, which uses the same outgoing interface in a higher priority queue, don't have shapers applied, the guaranteed-bandwidth may not be guaranteed any more. That's depending on how those all shapers are written as well as DSCP mapping config with the default queue priority. Probably nobody can tell exactly how it would behave until you simulate traffic and test it.
But generally you should avoid the possibility by applying proper shapers to all policies that go out to the same interface to get predictable behaviors. At least that what I would do.
