I would prefer drilling out the stripped threads and treating the eyelet as non-threaded, and just run a longer bolt and a nylock nut (or regular nut with star washer) behind the eyelet. French bikes came with unthreaded eyelets. It's a non-issue.
I prefer this to drilling out and tapping to M6. Tapping to M6 is certainly doable, but it removes metal from the eyelet, potentially weakening it.
