We all agree on what rest mass is, I hope. Relativistic mass is the
observed mass due to the object having this mass in motion with respect to
the observer. Do you mean gravitational mass as mass observed under
gravitational field? If so, how would these two observed masses applied to
cosmology to allow the conservation of observed energy?
