Yeah, I'm afraid that won't do much except eat valuable cycles.
IME the real problem with the CI tests is that the CI infrastructure
itself is not very stable, and intermittently fails tests for reasons
having little to do with the tested patch *or* the state of the master
branch. If there is a problem in master, we typically know it because
the buildfarm is also unhappy, so I'm not clear on what a null patch
in the queue would add.
