Does isotopic abundance differ enough on the various planets enough to think about producing planet specific periodic tables?

So the relative atomic masses on our periodic table are earth specific. Would there be a significant enough difference in isotopic abundances from Earth to warrant a change in these reported masses for that planet or moon?

The periodic table is really just a guide; anyone doing real calculations should have some idea of the isotopes (or distribution of isotopes) that are involved, and they would adjust the numbers accordingly. Furthermore, the mass of the elements on the periodic table isn't really a critical part of the periodic table. It's added there as an extra piece of useful info. The periodic table is characterized by its order by atomic number and arrangement of the rows to maintain periodic patterns.
