Is this possible? (Power question)

[Sorrel]

So, say a character has a sword, is it possible to change the shape of the sword using fire elementals to heat up the metal, using earth/fire elementals to shape it and then using air or water elementals to cool it? Or would it just be easier for them to conjure up the new sword? But I feel like the elemental power combination would be really cool and it would be a decently slow process it wouldn't be instant since cooling a sword too quickly can make it snap in half.
