Amateur idea for a better rp bot

I only know the very basics of what makes AI behave, but I just had an idea that’s either brilliant or a product of Dunning Kruger. What if there was a system in which several character AIs can be added and removed from a chat room, remembering what they’ve said previously in said room and having a list in memory of what bots are there and who they’ve interacted with? I feel this could lead to a much more cohesive story and less attempts to address a character who isn’t present.
