I would definitely allow it, without requiring a feat; It's mildly, mildly more powerful than using two light weapons to dual wield, but not enough to worry about.

something you might consider, since sword and dagger is fundamentally different than using two equal length weapons (the dagger is used more to parry and make opportunistic attacks against someone who gets inside the rapiers guard), maybe try an entirely new mechanic for it.

The Main Gauche: When holding a dagger or torch in the off-hand while attacking with a one-handed or versatile weapon in the main hand, the character has +1 to AC and rolls an extra d4 on critical hits. When used in this fashion, the dagger or torch is not considered a weapon.

Obviously this is meant to be an option for using a dagger in place of a shield for Duellists who want a little extra oomph (and for dungeon crawlers who need to occupy one hand with a torch)
