That would solve a few tech issues, but not all.

Kubernetes will cause incosistent channel states.

The core "feature" (or flaw, whatever you'd call it) is that LN is inherently secure and has a secure handoff to not have anyone cheat and duplicate channels and the funds therein.

Without state synchronization when one node or datacenter location goes belly up, one active node instance can safely manage channels at a time. Running multiple active replicas risks channel inconsistencies, as noted in discussions about LND’s database synchronization problems.
