However it would seem overly complex if it could. If a Hunter-in-training spent most of their young life learning how to use their Semblance, then woke up one morning and it had changed on them, they would need to start from scratch learning how to use it. This would be especially jarring if they had made their weapons around their Semblance (like Yang and Weiss). Even if there was a type of in-between phase between your Semblance changing from A to N, do they know they are going to loose their Semblance in place of another? This is even more unlikely if, as said above, Semblances are semi-hereditary.
