I don't understand the logic of "locking" tuners. They can't influence anything that happens from tuner tp nut,nut to saddle and saddle to pin hole, or tailpiece - whatever.
I have two perfectly usable 12 strings from the mid sixties with original worn 6 on a plate Waverley tuners which are far from perfect.
I think that the best approach to 12 strings is to
a) be able to identify the less than perfect note(s) out of 12, and adjust quickly and
b) accept that a perfectly tuned 12 string is an audible mirage, or a unicorn.
