My idea for a sequel that will never happen

At least a starting point. I know they scrapped any sequels after Gabor's death, but after recently watching both Rescuers movies on Netflix, I couldn't help but think of where they could go with a sequel. I thought perhaps Bernard and Bianca had a son, since Bernard proposed to Bianca at the end of Down Under, and he was the central character, recently begun working for the Rescue Aid Society. Bernard being not only a father but a mentor for him, and even give him examples of how Bianca encouraged him when they first started working together. They could even pay tribute to Eva Gabor with something like a portrait of Bianca at the RAS on a wall where past agents are honored. One line that always goes through my head is Bernard telling his son: "You know, if it hadn't been for your mother, I would have only been a janitor."
