The Duggars also mentioned the special in their statement on the cancellation, writing that they "look forward to working with TLC" and "hope that it is an encouragement to many."
Now, a source at TLC tells PEOPLE that Jessa Seewald and Jill Dillard will indeed appear in the documentary, which is in the early stages of production. Both women have come forward as molestation victims of brother Josh Duggar when he was a teenager.
TLC is partnering with child protective organizations, the Rape, Abuse & Incest National Network and Darkness to Light, to raise awareness and offer families dealing with similar issues resources.
"We realized just how huge and devastating the issue of child sexual abuse is around the U.S," the TLC source explains. "We felt there was a conversation happening because of the Duggars' situation, and we wanted to do something to move it forward."
Dillard, 24, and Seewald, 22, discussed the scandal on Fox News in June, saying they had "moved on" long before a police report on the incidents resurfaced this spring.
"I think all the people in our lives, like our close friends and the people – the officials – that helped us, walked alongside the family during this time and walked us through some of our hardest days, they knew about this. It wasn't like a complete secret," Seewald told Megyn Kelly. "People knew. They had walked us through this journey and we felt it was a done deal."
Josh Duggar, 27, welcomed his fourth child, daughter Meredith Grace, on Sunday. Dillard, her husband Derick and her 3-month-old son Israel recently moved to Central America for a mission trip.
