I like Thief THIS much
There are publishers who are already doing this to some degree I suppose(Microsoft, THQ Nordic?)
Devolver Digital is specialized on cool indie titles. Most of them are good. https://www.devolverdigital.com/
Games in their portfolio include Hotline Miami, Enter the Gungeon, My Friend Pedro, Reigns, Broforce, Ronin, etc.
Then there's New Blood Interactive which is both a dev and a publisher (I think). They're behind Dusk, Gloomwood, Amid Evil, Maximum Action. They focus on low to mid budget boomer shooters that look and play like they're 20 years old.
Both these publishers know their niche and especially Devolver knows how to spot games that fit their portfolio and grabs them. Considering the relatively small budget of the games they publish, but the high popularity of their top sellers (stuff like Enter the Gungeon and Hotline Miami) they're making big bank with their business model.
