Yes, but switch to what? Certainly nothing from ITF or Shotokan forms. The typical fighting stance we see for boxing, kickboxing, muay thai, MMA (to a lesser degree) is a similar relatively high stance with a fairly even weight distribution.
Apseogi isn't actually straight up, by the way. The weight is more over the front foot. It is a representation of a mobile fighting stance, and is certainly closer to the realistic starting point that many other TMA stances.
Now why would you bring Sport Fighting into the discussion? Different sports have different stances and guards. I am talking about the real world of fighting an attacker.
