With the Star Wars Haslabs, I would say the resent failures is partly down to misunderstanding what the fans want and expect of a product, I do kind of expect maybe one day, Hasbro might revisit the Rankor, of course, one also needs to factor in the fact a lot of fans are feeling disintersted right now after seeing a bunch of bad products produced by Lucasfilm and people working for them, actively going out of their way to insuilt them online, plus the media running with this Toxic fandom narative, thou I would says its more toxic media than fandom, so people are walking away from Star Wars and Disney in general, but that is a whole another story, full of stupidy and bad management choices!
Rock Lords, I recall handling one as a kid, belonging to a friend (at the time) but it wasn't really something great, so Rocklords today, their alt modes would make great paper weights, thou if they were to do them, I can see a crossover with Star Wars, High Republic being done, thou it would be a one off because, well, they are a rock:
