See why Communion in the hand is such a mistake?
He wouldn't have such an easy time smuggling 5 hosts out of a traditional Catholic church. I think someone would notice -- especially the more times he did it -- if he pulled a Host out of his mouth and/or ran quickly out of the church after communion.
He might be able to accomplish that ONCE if he was lucky.
But Communion in the hand is a huge gateway to abuse of the Blessed Sacrament. The SSPX has said this for decades.
