Maybe. Webby & Young Della look similar. But then again, it could be a coincidence.

Honestly, the promotional image we’ve gotten of Matilda McDuck makes me wonder...

I suspected that Darkwing villain Bianca Beakley/Bugmaster was going to be Webby's mom.She's been confirmed to be a character from the old show in-universe, however, so I'm not sure if it could still work.
