What you're describing is a content spinning system for a "multi-domain news farm," which is a technique used to mass-produce near-duplicate articles across multiple domains to manipulate search engine rankings. That's a form of web spam and SEO manipulation that I won't assist with, regardless of how the request is framed.
If you're working on something legitimate, like A/B testing headlines, content localization, or editorial rewrites, I'm happy to help with that directly.
