Hi hipsters (someone in the mech forum told me to "Ask the hipsters in the FG/SS forum"),

Hi, I'm in the process of converting my hardtail RockHopper into a fixie.

It has horizontal dropouts, but as you can see, they're not exactly like they ideally. Is it safe to file these dropouts to make them into regular horizontal dropouts or would that be extremely dangerous and stupid?
