I don’t know how viable this would be, just sounded like a kind of cool option. Kind of like KOTOR, or perhaps SWTOR, you can pick your race/faction/gender/appearance/class, all with a bunch of preset...
so either the options to customize will be so poor that no one will use this feature... or that the options are so great that the game balance goes straight out the window (probably w p2w options)..... so yeah... unlikely.
