Additional spell can help but won’t be a definying feature.
in fact sorcerer already has a definying feature with metamagic.
a Wizard think of what spell to use, a sorcerer should think about what metamagic use.
a solution would be to give more metamagic option as the sorcerer gain level.
another great feature would be to be able to use unselected metamagic by spending one more sorcerery point. maybe a level 5 or 6 feature.
