Current inquis build split?

[Jastarn]

I've decided I want to keep a dedicated capped raid toon, and since I have hallowed splinters on one of my alts, an Inquis xbow user seems the logical way to go.

A split I'm thinking of is arti 2/rog 3/Paladin 15, Inquis capstone, KotC core 4, Stalwart stance, then low hanging fruit from other available trees. Artificer for rune arms, rouge 3 for the seconds sneak attack die (think thats better than the 16th paladin level, since I don't see anything specifically important that I get from 16 paladin?), and paladin for survivability, healing, dps, Holy Sword.

Thinking of this split because it should give me reasonable (if not tippy top end) DPS, backup healing capabilities (with LoH, especially if I go Aasimar), trap skills, and survivability (via evasion/paladin stance). I'm not a power gamer or anything, so I'm not looking for advice on how to squeeze every last drop of damage out of an inquisitive build, but if anyone has advice on how to hammer out this build idea I'd welcome it

EDIT: Another thought I'd had would be 12 ranger/6 paladin/2 arti, would lose out on holy sword, and some light dps/utility from the level 12 kotc core, but would gain favored enemies/DWS enhancements... so many options
