How can we get more in depth character customization?

Probably, SE has pretty much written off the 'multiple Jobs/roles branching off one class' experiment as a failure, so you're not going to see a repeat of ACN splitting into SMN and SCH with any other class branching into multiple Job roles.

As it is I strongly suspect that Yoshi is considering removing SCH from ACN completely and making it it's own independent Job (it's already shown as independent of ACN in the list of classes in the player search window, and most weapons SCH uses are unique to SCH only, despite still being listed as 'Arcanist Grimoiries').
