Sounds like a clear violation of your rights. I am sure that you are right and the only reason you were pulled over was because of the CA license plates. The problem is civil lawsuits are about damages (i.e. injury, medical bills, pain and suffering, embarrassment, etc.). Probably, your only damages are inconvenience and annoyance and are not worth filing a claim over. You can always file a complaint with the law enforcement agency.
