Erm...I don't think it would work out like that/ The Shin'eiyaku were designed specifically for Shinigami use, and introduced Hollow Reiatsu to the soul of those wielding the user's Bankai - if they were Quincy, this injured them and caused a stolen Bankai to return to its wielder. It also changes the physical appearance of said Bankai to some degree. Since Orihime doesn't have Bankai, as she is not a Shinigami, I don't think it would do much, if anything, to her.
