Thanks to a post by Jens D https://the-disoriented-ranger.blogspot.com/2023/01/lots-of-ducks-no-row-and-gallery-of.html I noticed mention of a game being designed called the above, which sounds like fun.
Last month Marcia at Traverse Fantasy did some cluster analysis of OSR type rulesets.
People asked about where others fit in.
Idle thought is that with CC and other open licensed games – those that are adjacent you could slice up into the relevant sections – and randomly roll for each.
A function could even feed the classification into Marcia’s breakdown of rulesets as above to get ‘synthetic’ data for said clusters.
