A feat-intensive way that cuts slightly into paladin advancement but makes your point buy a little easier might be to play a strength- and cha-based falcata swashbuckler 1/paladin x.

Your human bonus feat would go to Artful Dodge, and Swashbuckler Finesse means your Cha counts as Int, which in turn counts as Dex, meaning a 15 Cha gets you up and running at first level despite only 12 Dex, and your Cha headband upgrades will let you take higher TWF feats later in the game. Use a falcata in your main hand and a kukri in your off hand, until you can magically diminish the penalty for one-handed weapons in your off hand (maybe around the time you can afford feats that are weapon-specific?) The major problem is that an Effortless Lace isn't strictly a weapon property, so Divine Bond might not let you fake having the feats to make one. Check with your GM. The nice thing is that RAW characters are all ambidextrous, so you can use your bonded falcata in your off hand when full attacking and in your main hand when AOO/riposte/standard-action attacking.

The suggestion /u/iamasecretwizard made, of Tempered Champion, works if you're building your own deity & can make your particular sun god's favored weapon a falcata (not too implausible a choice for a sun god, frankly).
