The GNU Name System https://gnunet.org/en/use.html already has a distributed DNS-like system built out.

This does not look like something my grandma would use.

I don't think she has to. As long as your ISPs run GNS themselves, and offer you DNS via DHCP, then you can just forego the ISP DNS server and drop in your own local GNS. Mount .com and the other TLDs you want from direct from ISP off their pubkey, and overwrite the TLDs you don't care much for.
