I never used more than one Vega on my system, but it is commonly know that at least two Vegas work without any issues under macOS, while you have to dedicate separate SSDTs for you each of the Vegas in use by considering the respective slot population.
I remember that @flymovies was using a hybrid Vega/Nvdida system by employing his Vega under macOS and his Nvidia under Windows (no web driver installed under macOS). I myself consider Vega/Nvidia hybrid configurations under macOS as critical and I would rather strongly discourage from such macOS hardware configurations. Maybe somebody else successfully driving a Vega/Nvidia hybrid configuration under macOS can oppose my personal impressions.
Thus I would rather recommend two stay with Nvidia in your case or opt for respective multi-Vega but Vega only implementations.
I used HD7950 (for viewport) and a GTX580s (for CUDA) in one system some time ago without problems. I wanted to do it again because of AMD great support (theoretically) in macOS.
