Since I presume you have verifiable backups of your pool couldn't you just remake the pool with the increased number of disks and copy back to it?

Recovering from my current backup solution is expensive, the additional cost is not worth it.

Remaking the entire pool is also a hassle and incurs unnecessary downtime.

Additionally, not all data is backed up, which I will loose, as this is not important data, it's okay to loose during a house fire, but not just for resizing the disk.

Lastly, this operation would likely take a long time, days probably, I'd rather just be able to just ram in another disk and be done with it.

I had assumed you would have a second array as backup for the current pool ensuring zero data loss and easy backup. This would seem to be optimal. Remote backup is obviously a good thing to have too.

Such a solution is extremely expensive and inefficient for a home setup.

All things considered your house will probably never experience a major disaster remote storage has got to be many times more expensive.

Remote storage is on B2, several Terabytes, it's not very expensive, restoring however is.
