A Question Regarding the Giant Shurikan...

If a set of secondary main weapons were made possible to be wielded by most/all job classes in the future in order to create more variety within each job class and to give it a second identity so developers wouldn't have the need to make a set of new job classes for every future expansion, would a giant shurikan as a second primary weapon work out for Ninja? I ask this question because I've always been a big fan of Yuffie Kisuragi from FFVII and was actully a bit disappointed when I found out the Ninja job class would only be able to wield knives and daggers, and not a giant shurikan as its main weapon...

Other than my own question, what types of weapons do you think would work out for other job classes as second main weapons and how would they and their skills/spells and abilities function differently in comparison to their current singular main weapons and skills/spells and abilities?

Personally, I think a Giant Shurikan would be a great secondary main weapon for Ninja since it could transform the job class into a ranged support class that deals heavy damage while supporting allies skills and abilities that would help immoblize enemies, and cause various status and damage over time effects. And regarding ninjutsu where the giant shurikan already exists, if giant shurikan is equipped as your Ninja job classes' main weapon then the giant shurikan ninjutsu would be replaced with a ninjutsu that could some multiple Giant Shurikan in order to deal multiple damage to either single enemy or taget multiple enemies at once.
