What would be the best way to include Dewey?

I 100% respect Erik Per Sullivans decision to not act anymore, and I doubt that he’s coming back for the revival. That being said, what’s the funniest way they could accommodate this? I think maybe an ongoing background gag with posters/references to Dewey being some famous celebrity would be hilarious, maybe Lois could have a fit about how “our son thinks he’s so famous, that his own blood isn’t good enough???”
