At a New York Comic Con panel for the Hidden Temple movie, Nickelodeon's VP of original movies, Michael Sammaciccia, said it wasn't out of the question.

In fact, he said many of the classic Nickelodeon properties were being considered for revival, not just Rugrats. See for yourself:

“What’s happening with [Legends of the Hidden Temple] is that it’s allowing Nickelodeon to look at the rich library they have, and not just Rugrats. All of them are being considered.”
