No, in fact people are already building tools like this especially special interest groups. I imagine it could be quite lucrative to sell a framework that does this. Though I'd note IANAL. Thus this isn't legal advice. That said, such a tool isn't unethical. Setting aside the fact it's also legal as best i can tell (which you seemed not to know) you should consider the following: If something, generally speaking, is not unethical, and indeed adds value to the world without causing meaningful harm to anyone, should you avoid doing it merely because the government could disapprove?
