Huh? So far as I know changing the elemental type of the spell is approved even in official rules (by GM's decision) when re-fluffing spells. You cannot add dual elemental type to spells which do not have it already but change acid to fire example is minor change.<br/><br/>It ruins my concept to nothing if I cannot swap elemental dmg type to fire with spells which I choose, or change them. I did not plan change all spells, as theme wise I thinked my char has fire or thunder spells but nothing else. But if I use thunder or fire spells it skips some spells which mechanically suit to the dragon soul or overall are nice. I am not aksing change damage dice, feats or class features. Just elemental type of the spells. Go even so far if I example change frost spell to fire spell then defense would change to reflex instead fortitude (as it makes more sense).
