That's the way it started with smoking on airplanes.
My recollection is that the priest or altar boys start at the back and work their way to the altar with the incense.
Of course, the candle smoke is endemic.
Won't work.
And there are kids in there - infants being baptised.
Sorry, that's a non-starter.
As a former altrar boy let me just say that knowing what you are doing with the censor reduces the quantity of smoke so that it should not bother people. Of course sometimes we liked to see just how big of a cloud we could produce but that is another story.
