Off the top of my head...

Futari Wa/Max Heart: Hikari's daughter

Splash Star: Flappy and Choppy's kid teaming up with Minori

Yes 5! GoGo: The first male duo with the sons of Nozomi/Coco and Komachi/Nuts

Fresh: Love/Daisuke's daughter alongside her friends who are also daughters of the other Cures

Happiness Charge: The son of Megumi and Seiji

Mahou Girls: A girl adopted by the main duo Cures

KiraKira: Miku and Pekorin, all grown up

Star Twinkle: Not sure about this one

Healin' Good: Same especially since the series hasn't premiered yet

Cyberverse: We got a classic gogglehead duo with Agumon and Gotchiman teaming up with Saiba's kids

Sporty: A new duo formed from the nieces of the main duo

Prism Hearts: Mina, all grown up

Shinobi Stars: The son of Kaguya, who would also serve as a reference to Kamen Rider Shinobi

Color Splash VS Insector: Ruki and Wataru, who have a pair of beetles as their mecha (kind of a Gouraiger/Thunder Storm Rangers reference)

Treasure Trove Precure: A brand new generation of Treasure Trove Pirates

New Generation: Kind of a surprise as they would serve as the main characters alongside the main cast of Cures

Mysterious: In a change of pace, the whole team shows up to make an assist (technically they don't have kids yet but this would serve as a nod to how the Treasure Trove Precure team debut)
