Magical Unarmed Strikes

[TruthRevolution]

I've been reading up on the Magus class.
Am I right in thinking that a magus could cast Stone Fist and Chill Touch to gain very powerful unarmed strikes? Or something like Corrosive Touch or Elemental Touch would also fit the bill, I'd think. Those spells discharge on touch, right, so they don't have to just touch their opponent, they could be striking with their fists?

Those spells do dispell on touch, so if you make an unarmed strike, you can discharge the spell, but you still need a melee attack roll (not a touch) to do damage with your fist.
