Depending on bandwidth, you could probably stream an over-rendered viewport (e.g. 3D skybox) that allows for local-device-magnitude latency for critical functions (perspective change & location translation), while being backed by streaming servers (especially of the edge variety).

I suppose in the future, anything is possible—but I don't see it. You're asking the local device to do Z translations of a 3D scene when all it has is an already-rendered 2D image.
And the local device will just have a 2D image. Even within a single, local PC, multi-GPU rendering is basically dead for video games because no one has been able to get them working reliably. And that is with the full bandwidth and latency of PCIe.
I don’t think even 5G is low latency enough for what you’re describing—not even close. Stadia works because it’s not VR, so they have some latency headroom. For good VR (Valve Index, etc), you get around 20ms for the entire rendering chain.
