Would a post true ending DLC ruin the emotional impact of the open finale?

The bitterswet finale was perfect. Is it possible to develop a full Marcole DLC given that the foundation of Mark and Nicole relationship was trauma/grief? Their chemistry was great but is hard to imagine a full a chapter without the jake/mark's mom conflict.

Maybe a one final meeting or dating scene would be nice (like the steins gate S1 finale) for the fanservice
