You're right - the Bronco II was a two-door only, but they effectively replaced it with the first-gen Explorer.
That said, though re: the Bronco II, the number of safety advisories it had...including warnings about driving uphill...are indicative that it didn't solidify itself as a memorable vehicle like the OG Bronco is (at least not in a good way). As you mentioned with the Blazer, that's still a recognizable vehicle that lasted for generations, but I don't think many people remember the Bronco II and look back on it terribly fondly.
