Well, I'm sure the writers can create completely different characters if they want to with the same initial data. Suffice it to recall that in Kiva, Yuri and Megumi are both tough but vulnerable monster huntresses, avenging their mother and giving in to IXA to their love interest. But with the same description of the characters, when watching the show, they are perceived as completely different. I think the same can be done here as well.
As an example, the new rider Ranuki (quite a logical name after Tacoon, isn't it?) can be just as naive, but instead of confronting Ace (ideological, because Michinaga is responsible for the physical), admire him and try to imitate him. This will create a completely new and different dynamic. By the way, what do the three bears have in common, besides a quick departure? Maybe a clue can be found in their example.
But in fact, I would be very surprised if Keiwa was removed forever or even for a long time. If only because the show left a plot hook in the form of the cause of death (or rather not resurrection) of his parents. This will most certainly be revisited, so either Keiwa will be reinstated for the next DGP; or Sarah will be made a rider instead.
As a completely crazy option: Boost and Ninja buckles will fly to the civilian Keiwa, restore his memory and return him to the game.
