If somebody wants to replace eye-rhyme and ear-rhyme with correct terms, be my guest.
Here’s the idea, though, brought to mind in a recent thread where fun is being had over the correct pronunciation of OG. It occurred to me that regional variations can account for why not all -og words rhyme. In my case, dog is an oddball to fog, cog, log, hog, etc.
The idea is to locate some short (3-to-5-letter) words that have the same vowel in print but a different, non-rhyming sounds when spoken. Here’s a group that almost rhymes, but has at least one non-ear-rhyme:
ban, can, Dan, fan, Han, Jan, LAN, man, Nan, pan, ran, tan, van, wan, Yan (the missing starting consonants may have words that exist for them but I couldn’t think of example words offhand).
Come up with a group that has eye-rhyme and ear-rhyme with many starting consonants. Otherwise, find a group that almost works.
Expand on the idea if you can. A way to abuse a Thursday at least.
