Yes nier is perfect. The other best option is kingdom hearts III(the best title in the series). The darkness and ending of the world is perfect for both IPs. Maybe a KHIII collab next year would work too since they already have SE greatest writer and art director Tetusya Normua helping with the raids. I just gain infinite more trust in yoshi when he explained how much of a genuis he is. Nier or khIII both perfect for this xpac-become darkness itself
