Could it be excluded that the Hubble red shift and the greater than
expected rotation rate and implied increased mass of distant galaxies
could be explained by mass decreasing with time?

No. Cosmological redshift would go with an *increase* in particle
masses over time, if that is what you mean by "mass decreasing with
time".


I implied that masses might have been greater in the far distant past, and
less in the here and now, so that the light goes uphill.
