I mean... the test case already exists, Memoria Miseria normal.

So they can definitely make Trial content with Trusts... but can they make Trial content that can be done interchangeably with Players or Trusts that retains a modicum of difficulty when done with players... iunno.

I'm leaning more towards probably though when I think about ShB Trials... the normal modes don't have anything particularly difficult that I think an A.I. or script wouldn't be able to handle.
