That is possible on some LTE networks already. It is pretty trivial for WiFi.

All these figures are always giving best case scenario, i want a 50% saving in low end, 2-4Mbps range.

Last time I read, VVC communities would actually like to push for more than 50% savings. I wonder if that is still the case.
It's hard to predict the savings of a new codec without production-ready encoder implementations, but everything I hear suggests that VVC is quite plausibly capable of delivering the same perceptual quality as HEVC at half the bitrate, with encoders with similar degrees of development. It'll take a while before a generalized 50% would become available, though, as HEVC encoders are way more mature. There's more scope in adapting a VVC encoder from an HEVC one than, say, a AV1 encoder from a HEVC, since the foundation is a lot similar. One could take an existing HEVC encoder and start adding features from the VVC reference encoder and get to a compliant bitstream pretty quickly, and then start iterating on newer tools and quality tuning.
