Are small ceph clusters viable?

I sincerely recommend checking out Microceph, it is designed specifically for smaller edge clusters and Homelabs.

  Small helper scripts for monitoring/managing a Ceph cluster

I've been very happy with my cluster. I've been slowly upgrading my drives as well to larger capacity... buying a couple of drives a month to spread the cost out. It's going well though I do find I have had to resort to a scripted reweighting to make it "gentle" or my performance does tank during the build of the replaced drive (I use this script to do the reweight and it works like a champ)

  backy2: Deduplicating block based backup software for ceph/rbd, image files and devices

Overbuilt and OTT? Sure... but this works fantastically for my use case. I have current backups of everything except my media library because of the size of it; my VM's are all backed up to my Synology nightly using Backy2, my application data gets dumped to that same Synology NAS nightly as well, and all of that also gets synced to Glacier deep storage once a week using Duplicity. I'm going to be adding a new ZFS array later in the year to replace my Synology and hopefully I'll build it out with enough storage to take my media library as well.
