The following have all changed. They are not dependent on c.
Planck's Constant
Electron Mass
Proton Mass
Gyromagnetic Ratio
Magnetic Flux Quantum
Josephson Constant
Electron charge-to-mass quotient
e/h
All have been shown to have changed between 1969 and now as published by CODATA.
These are not dependent upon the size of the meter!
And, again, any possible change in the size of the meter is far outweighed by the measured changes in the speed of light.
Suggest you actually read the material and not simply harp on this one moot point.
