JP16 Locking Tuners

I would like to upgrade/replace the Schaller M6LA tuners on my JP16 to locking tuners. I know they are not necessary with the Floyd Rose. I just like the convenience/ease when changing strings. Does anyone know what the Schaller locking replacement for the M6LA tuners would be? I am looking for a drop in replacement. I don’t want to drill extra holes. Thanks!
