Quincies aren't weak to Hollows and their hybrids; look at what they've done to Hueco Mundo. They just can't take it when Hollow Reishi gets into their souls. Shinji's mask would power him up a lot, and he'll have to use it sooner or later, however none of his attacks would be "poisonous" to a Quincy, (unless he goes around biting Quincies with his mask on).
