I have a suggestion too - SOLDIER -
Weapon - Greatsword
35 - Braver
40 - Climhazard
45 - Cross Slash
50 - Omnislash

AF - Soldier outfit with requisite "Cloud Hair™" head piece.
Can meld materia without a profession also gains Knights of the Round summon upon acquiring job.

This is obviously a joke but you can see that anything is possible and we can only dream as to what is coming in the future~
