I think both Bocchi would vibe and relate to one another, and Hitori Bocchi would be like a younger sister to Hitori Gotou. I also found some coincidental similarities between their friends.

I played around with both Bocchi's similar designs by having them exchange hairpins and outfits. Both of them have an animal themed outfit too. Also both mangas are yonkomas, ain't that a crazy coincidence?
