Well the new anime might be a full original which continues from BorN by excluding Le Fay and some other major point though, if this does become an actual thing:

""There's a certain timeline in which the Seirei of the Chichigami did not appear.""

Ise in BorN is already stronger than the LN anyway. Same goes for the others like Saji. So things may be different if they decide to continue the story from BorN.
