I briefly considered the possibility myself. The main reason I discredited it in the end was Winter's comments about fallen foes being called to the user's aid, and the fact that Weiss's Summon was the giant armour's sword rather than a Grimm. The implication was that the beowolf form came from something she fought in the past, rather than being an original shape taken by the summon.
