Yup!
@Nico brought up another element as in the continuation of the games, but I think Suzanne's world has a lot of potential to show us he degrading reality that comes to the victors after the games; how they struggle and deal with the "train ride" that they are now essentially permamently on.
I think Panem has a lot of growth as a country and universe as a whole; especially if Lionsgate allows them to dive much more into how Panem works before the rebellion of District 13 interferred with the 75th games. Hell, you could even make a case to show a story of what it was like for those in District 13 as they had to flee and run from Peacekeepers; and to keep their humanity entact.
