Tbh I'd recommend trying nix on top of another distro or on top of OSX first. If you just want the ability to install arbitrary versions of packages along side each other/have painless roll backs/bake config files into your install you can do that there. Once you get comfy with nix on top of another distro then think about whether you want that approach with the entire stack.
