     That's called "swaging"  the key bushing.  Yeah, it works, once, as
someone else said.  But it's not permitted in the PTG technical exam and is
considered a "wood butcher"-type procedure.   But as there's no regulatory
agency for piano technicians, nobody can keep you from using it or suppliers
from selling it.
