not looking it up, just writing out of my head, and guessing the pronunciation...
nepozrel som si to, píšem len tak z hlavy a odhadujem výslovnos?...
Luua [lu-u-a], Luuy, Luue, Luuu, Luue, Luuou
Beau [bo:], Beaua [bo:a], Beauovi, Beaua, Beauovi, Beauom
Aimee [eimi:], Aimee, Aimee, Aimee, Aimee, Aimee
Luigi [luĭdži], Luigiho, Luigimu ... ah.....
.... you mean [fem.] ??
... (perplexed) ...
Luigi, Luigi, Luigi, Luigi, Luigi, Luigi
... that's what i would say

unfortunately, the Slovak declination system was not designed to make it possible to derive one form from the other unambiguously...
you have to go to conlangs for this ;)
