Your idea is ambitious, but completely infeasible to implement without a strong team of IT engineers and a solid piece of capital for investment. Cloaking companies like us are investing years and hundreds of thousands of dollars to develop and maintain contemporary cloaking services. It isn't nearly as simple as it was 10 years ago to build a cloaker because counter-cloaking technology is always evolving and becoming more and more sophisticated, their bots use machine learning, IP transit networks, ISP-side CDNs, and a lot of other advanced tech to catch you. You cannot just create an IP blocklist of IT datacenters and call it a cloaker. This is exactly why we employ things like JS fingerprinting and machine learning--because trivial IP blocklists do not work anymore. Remember, there's a good reason why cloaking services are expensive: because it is expensive and hard to build and maintain such a service, always keeping it up to date.
Of course it works. Cloaking market is thriving, and not just for Google and Facebook. Pretty much every ad platform can be cloaked, and there's no obvious reason for it to stop working anytime soon.
