Very similar in concept here would be a halfling all-into-Charisma and using Desna's Shooting Star for a kickass melee and ranged weapon. Then you don't need Dervish, among others means of gaining finesse, because that isn't necessary. The bulk of the build would be warpriest, which pumps the base weapon die, gets the DSS feat by swapping a minor blessing, and offers other utility to the character. (IMO the base warpriest is better than the more glass-cannony Arsenal Chaplain archetype, but YMMV.)
CON: 12 (halfling, 17,14,12,12,12,7 20pt array*)
(*or 15,14,12,12,12,12 array with GMs who frown upon minmaxing.)
racial trait: Fleet of Foot
character traits: Fate's Favored, Dangerously Curious
01 uMonk1 [Invested Regent][Move+10], DFT:Desna's Shooting Star
02 Cleric1 (worship Desna)
03 Warpriest1 (slide DFT into minor blessing & retrain 1st-level feat to Crusader's Flurry), Quick Draw
04 Warpriest2 CHA>20
05 Warpriest3 FEAT(g), FEAT(w)
06 Warpriest5 [Channeling], (retrain Cleric1 into a level of Warpriest)
07 Warpriest6 FEAT(g), FEAT(w), ...etc.
* Four open feat slots
* Paladin-like saving throws due to Investiture.
* AC = 11 + Dex + Wis + (Fervor buffs) + (UMD'd Mage Armor) + Bracers, etc.
* Flurry with same charisma-based weapon into melee AND ranged.
* Since dex/str aren't attack stats, a Blinkback Belt is painless.
Dip a level into Oracle for any of several revelations using Charisma for AC and Reflex or CDD instead of Dex, and that stat can basically be dumped as unnecessary for anything except bonuses to some skills.
Interesting build but hard pass on the 5 strength. Any number of things that are pretty common shuts you down.
