If enough followers of Bahamut (or perhaps Dalamud, which, ultimately is the same concept) were to gather and perform a summoning, then technically anything is possible (with the proper amount of aether to act as the catalyst), and it doesn't necessarily need to be on Meracydia (which, in many places is still a smoldering waste, even today). What needs to be understood is that the state of the believers when the summoning occurs directly affects the manner in which the dispersed essence of the deceased is reconfigured. Tiamat, knows of this first hand due to her failed attempt to resummon her fallen beloved. She and Bahamut's brood knew Bahamut better than anyone, but since their hearts were darkened by sorrow stemming from the loss, coupled with hate directed towards the Allagans, the Bahamut that was ultimately brought back ended up being naught but a twisted shell of the dragon Tiamat remembered. This also explains the differences between the actions and temperaments of other primals spanning from 1.0 to 2.0. The needs and desires of the believers doing the summoning changed following the Calamity, resulting in changes in the primals they summoned, Ifrit and Titan, even Shiva all being good examples (though Shiva's differences span back further than just 5 years ago).
