Oh no!
Unfortunately, my dad has a cat with this problem, too. 
He has hand fed this cat since kittenhood to mitigate the problem 😭 
I think a better solution would be to close the cat in a room with an easy to clean floor until a little while after his meal time. Then even if he throws up, you can clean it and then everyone goes about their day. 
But he’s never tried it my way.
