Nah. Pierce displayed quills primarily on his arms and face, though with a certain spikiness of his hair (I would argue that it is hair, rather than spines), and his powers centered on his ability to elongate and detach them. Porcupine seems to have spines in place of hair, and extending onto his shoulders. Pierce's are the color of his skin, Porcupine's are not. Furthermore, only Porcupine's displayed tranquilizing abilities. In at least some regards, Porcupine is more like Argit.

By the way, Porcupine has never been officially confirmed to be part alien. Ready to Rumble, for its part, implied its wrestlers to be mutants.
