Since I was a kid, I’ve always been fascinated by groups of words that differ only by changing the five vowels: bag, beg, big, bog and bug are all actual words.
Today, out of the blue, I discovered blander, blender, blinder, blonder and blunder.
Whaddya know?
Tan ten tin ton tun!
logological starts with “logo logi” but you already knew that
There’s also blynder, since “blynd” is an archaic spelling for “blind”, though that doesn’t add to your list a word with an entirely new meaning.
R_d. I did have to look up rud, but supposedly it’s a valid scrabble word. I imagine there are a lot of 3 and 4 letter variants that qualify where one of the vowels forms an archaic word.
It turns out that someone who writes bots has a job title the same as a “Flat-bottomed Dutch sailing vessel,” so there’s always that.
This is a job for … software!
My quick & dirty script produced these 98 results.

I have a feeling that not all of those words would be allowed even in Scrabble. 
daer?
gud?
roed?
steng?
taa?
wod?
and many more.
And others are either abbreviations (deg), archaic ('pon), or prefixes (mult).
A fun list, but dictionary.com is snobbish.
My favourite set.
Never been told to “git gud, newb”? 
“Filled with roe” - perfectly cromulent
That one has at least 3 valid meanings
Although I agree that a lot of them don’t work. Roed does, but roud doesn’t, for example.
My word list does have a lot of obscure and archaic words, but the six you call out are all in the OED.
daer: A beast: usually a quadruped, as distinguished from birds and fishes; but sometimes, like beast , applied to animals of lower orders. Obsolete .
gud: A euphemistic for god [n. and int.]
roed: Of a fish: carrying roe; full of spawn.
steng: dialectical for sting and stang in various senses
taa: archaic form of take
wod: variant of several words including void, wood, weed, wit, etc.
And “roud” is defined as
English regional ( Norfolk ). Now rare . intransitive . Of a fish: to spawn.
You can consider this list to be a superset of an acceptable list.
So is there a formal term for this sort of wordplay?
When I read this list, I pronounced the bolded word in my head as rhyming with “tinder”, and thought: “Blinnder?? That’s not a word!!”
Mmmm - addictive. I feel the need have a Y word too:
Dane
Dene
Dine
Done
Dune
Dyne

“Logology” was coined by Dmitri A. Borgmann to represent the study of recreational linguistics. He founded Word Ways, a magazine devoted to this pursuit, along with writing a couple of books on the subject.
Thank you very much for this list. It’s going in my vade mecum now.
I don’t care about the new meaning bit. I’ve checked the OED and W2, and they agree with you. So, huzzah!
Word Ways is still being produced quarterly by Butler University, IN. Here is its website complete with access to some free back issues.
Yeah, I always wanted to add “y” to the group, but they’re about as rare as hen’s teeth.
I’m a lot less picky than Scrabble or dictionary.com. Abolete archaisms are fine with me.
