Kubrick would have loved the high sensitivity of current senros, which makes it practical to shoot without artificial light* though it has to be said that film stocks have improved a great deal since Barry Lyndon was shot. But I'm much less certain about whether he would have embraced 48 FPS (not Hz, because we're not modulating a coherent beam). He had such technology fully available to him as far back as the 60s and chose not to employ it.

* Lighting is not just about making sure there's enough light. Some scenes look great just as they are. Most...don't. Your brain filters out a lot of what you don't care about it in the real world, but when you see it on screen it sticks out like a sore thumb. Lighting is more of an artistic than a functional thing in most cases, and is used to draw the viewer's attention towards or away from what the director wishes.
