I would not allow acro climb as s rule.Do you allow to a certain degree and in some cases Acrobatics and Athletics to be used interchangeably?
Climbing for example seems to be either Athletic and Strength-based or Acrobatic and Dexterity-based. A squirrel is not strong, but it climbs with the greatest of ease. A circus acrobat comes to mind as well.
I understand that for game balance, Dexterity does not need to be more powerful than it already is, but...
First there is iirc class ability for thief that allows it.
Second the native climbing ability done creature get is often represented with climbing speed - claws feature
Third I do not like blurring the line between attributes any more than happens.
