Not Splinter Cell but still reminds me of Blacklist and Conviction

In the trailer you can see one of the character mention something about their Grandfather believing the devil will return.Father Marcus probably imparted his knowledge regarding the deadites to him and he somehow wrote those in a diary or something.

Maybe the Father somehow survived and the deadites is just hunting his kin out of anger.

Waller's show would probably have been about her dealing with the aftermath of Season 1.The show probably would have featured her daughter heavily too.

Now with the ending of Season 2 of Peacemaker and how Flagg has become the defacto leader of ARGUS.Waller teaming up with her daughter to take control back from Flagg would make a good premise.
