Found this article about why there might not he a remake of said game.



"Sonic Adventure fans might not be happy to hear this, but there aren’t any plans to come out with a remake or remaster anytime soon.

Takahashi Iizuka, head of Team Sonic, was recently asked about revisiting the game in an interview. The takeaway here is that Iizuka believes it’d take a huge effort to bring the experience up to today’s “standards and expectations” – as much as a new title would apparently. Because of that, he feels working on a new game instead makes more sense.'

Iizuka has also shown interest in making Sonic Adventure 3. However, it’s unclear if that’s still something he’d want to pursue."- Nintendo Everything

I'm fine with that. If they choose to create an actual sequel to those games then there's plenty to speculate about than remastering existing titles.
