I doubt it's canon. If it is, Kubo hasn't shown it, to my knowledge.

I hope Kubo have made Grimmjow stronger, so that he can join the battles against the Stern Ritters. As far as we know, they can only steal Bankai, I doubt the can steal Resurreción. That would have been interesting to see in any case, it would in such a case have to be the techniques the Arrancar has in its Resurreción.

But Grimmjow killed Kirge with a single vertical slash. If Kirge was a Stern Ritter, which I hold possible given the power level he apparently had, he could do well in battle against them.

It would have been funny to see Grimmjow take on Royd and fight an imitation of himself :P I imagine he would get pissed that someone were rude enough to imitate him and use his attacks against him :P
