Share 'Fret Slots too Large?'

Hey all. I beveled my fret ends too much (strings slip off the fret), so I'd like to refret the neck. I'm concerned when I remove these frets the slots will be too large because it will be the 2nd time I've pulled the frets. What are my options if the slots are too large? I was thinking hide glue. But does it need wood shavings mixed in with it? Thanks!
