  Utilizing a setup of type IIB superstring theory compactified on an
orientifold of T^6/(Z2xZ2), we propose a modular invariant dimensional
oxidation of the four-dimensional scalar potential. In the oxidized
ten-dimensional supergravity action, the standard NS-NS and RR three form
fluxes (H-, F-) as well as the non-geometric fluxes (Q-, P-) are found to
nicely rearrange themselves to form generalized flux-combinations. As an
application towards moduli stabilization, using the same S-duality invariant
scalar potential, we examine the recently proposed No-Go theorem (in
arXiv:1409.7075) about creating a mass-hierarchy between universal-axion and
the dilaton relevant for axionic-inflation. Considering a two-field dynamics of
universal axion and dilaton while assuming the other moduli/axions being
stabilized, we find a part of the No-Go arguments to be quite robust even with
the inclusion of non-geometric (Q-, P-) fluxes.
