It’s a great idea, but don’t forget about how these people are going to get support in the future. If something breaks, most helpers (computer shops, kids friends etc) are going to be Windows users.
Mint can do automatic updates, but both my laptop and PC have had serious issues with version upgrades. My laptop, which is Mint only, asked me to remove a load of software before upgrading, then booted with loads of errors and had to be reinstalled. My PC was mostly fine, but had no sound. It turned out that Mint switched from Pulse Audio to Pipewire, or vice versa, and the old audio manager left config files behind.
They were both annoying issues more than anything else, but would be difficult for the people in your scenario to get fixed.
Don’t get me wrong, I’m not trying to put you off, just checking that you’ve thought of the downsides :)
That’s brilliant, I hope it all works out 😊
