Even if you miss the warnings about not being able to return from the Hall of Echoes (Patriarch strongly implying things didn't go very well for Maxos, etc), entering is obviously a significant plot point, so a good place to make a save before proceeding.
Anyway, in DKS/D2:DC you can reach a slightly higher level by the time you get to the Hall of Echoes compared to the original release (I finished D2:ED at level 36.75, in DKS I was level 37.47 at that point). The level influence of combat was also reduced, so entering the Hall of Echoes at lower levels wouldn't be as much of a problem. In D2:ED a couple people were able to complete the final battle on level 30 or 31, and one reported finishing at level 26 (near the end of
Ygerna's memory battle - I hate you!), though with a very indirect technique.
