I guess if they are regular, you can describe a rule to manage them... I don't mean this rule should be easy to implement. I'm working with Spanish verb system and taking recognisibility as goal. I have no problem with regular verbs. I have no problem with some regular irregularities as o/ue - e/ie changes or -ecer, -ezco endings. For completely irregular verbs like _ser_ or _ir_ I have implement them by adding irregularities as part of the lexicon. If that is what you mean by mutation, I guess is no way arround. If you mean regular changes like o/ue, or like voice/devoice you just have to write the rule, and implement your lexicon in some way that help the program to recognize where the change is needed.
