Nah, unarmed strikes are different from natural attacks, which have to be made with natural weapons (claws, bite, tentacle, slam, etcetera). If your race already has a natural weapon, like getting a claw attack, then you can make some serious use of the spell (because you can full attack with them like that, since it's not the class feature requiring a standard action), but that's not exactly a common thing; the only two races that are viable for a Blue Mage and have a natural attack are burmecians and shindroids, both of which get a somewhat inferior attack (bite and slam respectively, both doing 1d4). A Primal Mage would be great with it, but you're giving up all your Blue Magery to be able to bite super hard, and Murderous Might isn't going to be a thing until you're at least 15th level anyway.
