pegheds on a 1962 martin style 0

I would like to know if anyone has ever transformed his martin with friction grover into pegheds? It seems it is a irreversible process or is it?
I would love to have a precise and easy tuning device on this ukulele.

I've thought about this. I've been wanting a 50's Martin Tenor Uke for a LONG time now. If I ever get one it's getting peghed tuners

My theory is, if it's your uke, and you plan on playing it go ahead and make it better
