Remounting bindings in plugged holes

So I just bought some used skis that have been mounted twice and I'm trying to avoid drilling them a third time. The original mount is for pivots at my bsl, but sadly those holes were plugged when the second set of bindings were put on. Would it be possible to remove those plugs and use the original mount holes again for my pivots? Does anyone know the best way to remove plugs? I saw some old threads that said to just redrill into the same holes to get the plugs out but I figured id check to see if anyone has experience doing this before I try.
