Starting with type IIB string theory compactified on an orientifold of a SwissCheese CalabiYau expressed as a degree18 hypersurface in the weighted complex projective space WCP^4[1,1,1,6,9], in the presence of a mobile spacetime filling D3brane and fluxed [stack(s) of] spacetime filling D7brane(s) wrapping the 'big' (as opposed to the 'small') divisor, we give a geometric proposal for obtaining a supermassive gravitino in the inflationary epoch and a "light" gravitino in the present era in a single setup. We also show that the setup naturally realizes a "musplit supersymmetry scenario" wherein having restricted the mobile D3brane to the big divisor, one obtains supermassive D3brane positon moduli  identified as the two Higgs doublets  at the string scale and after 1loop NathArnowitt RGevolution to the EW scale, one obtains one light and one supermassive Higgs doublet. Also, the fermions (quarks/leptons) corresponding to the fermionic superpartners of the Wilson line moduli, are very light but the Higgsino mass parameter is very large. I also discuss issues like neutrino masses, gluino and proton decays. As a bonus, I will discuss obtaining the geometric Kaehler potential (relevant to the moduli space Kaehler potential in the presence of a mobi le D3brane) corresponding to a Ricciflat metric for the SwissCheese CalabiYau used in the large volume limit using Gauged Linear Sigma Model techniques for obtaining the geometric Kaehler potential for the big divisor, and the Donaldson's algorithm for obtaining Ricciflat metrics, as guides.
