IMO, there is no reason to make a Finesse build unless it is also an AC build. And a well-played rogue should never have aggro, and therefore probably doesn't need AC... And if said rogue had aggro, they would probably want low AC+Radiance Guard to finish off whatever is killing them quickly, rather than rely on AC to draw out the fight.
I would make a rogue a Strength build with minimal dex (15 base, +2 tome) for feat prerequisites. Making a strength build, in addition to doing more damage than a finesse build, means that you can use whatever weapon you feel like--you are not restricted to Light weapons.
