1. You should not be using K3OS anymore, its a dead project. If you need an immutable OS look into opensuse MicroOS potentially.
2. I don't believe there is a way to just do the bootstrap. If your running the cluster with embedded etcd, you may just want to look into doing a snapshot and then restoring on the new cluster. https://rancher.com/docs/k3s/latest/en/backup-restore/

Unfortunately we are behind the curve on this news and we are working on a plan to replace K3os. The lack of official notification on this really bit us in the rear as we just happened to stumble across a github issue last week that included a conversation with a Rancher representative mentioning that K3os was a dead project.
Thank you for the suggestion, I will look at that as an option.
To that end Is there or will there be an upgrade path that will enable us to migrate from k3os to RancherOS v2 (https://github.com/rancher/elemental) that wouldnt require us to re-image/re-build the clusters?

fwiw we had a similar scenario (albeit not with k3os) and now end up just sticking our clusters behind a router, so we can control the IP space on our side
