How about a crossover with 'Victorious'? Tori Vega could be invited to perform at the school where Teddy and her siblings go. Tori and Teddy could become friends and work on a project together. Meanwhile, the rest of the Victorious gang could have some comical interactions with the other Duncan family members, like Robbie trying to impress PJ with his puppet Rex.
One idea could be a time - travel plot. Maybe Charlie goes back in time to meet her parents when they were younger and has to make sure they still end up together. Another could be a 'what if' scenario where Teddy never made the video diaries and how that would change the family dynamic.
A more dramatic plot could be that Lauren has some complications during her pregnancy. The family then has to come together to support her and deal with the stress. It could show how they all grow and become closer through this difficult time.

One idea could be a crossover with another popular animated show. For example, the characters from 'Loud House' could end up in a different universe where they have to use their unique skills from 'No Such Luck' to survive. Maybe they meet characters who have similar family dynamics but different challenges.
One idea could be a crossover with the 'Mission: Impossible' series. The Angels could team up with Ethan Hunt's crew to take on a powerful international criminal organization.
