Next Upgrade Steps for Spark (Goal of No-hit Sanctum)

I'm trying to determine the next cost-effective upgrades for my Spark Aura-stacker Inquisitor. I have Mageblood and just acquired Ashes. I'm mostly doing Sanctum and occasional Heists. Full-time Dad, so currency flow is kind of slow.

I'm currently at about 5M DPS.

After browsing PoeNinja, the next major upgrade packages look like:

1. Gloves with Faster + Slower Projectiles and Fast Casting. 20-100 Div, 25%-50% DPS
2. Divine Blessing package (Div Blessing/Inspiration/Arcane Surge). This moves an aura (Wrath?) into Blessing and allows Haste into the main aura set. 6 Div, 25% DPS.
3. Nebulis w/ 10% Double Damage. 50 Div, 10% DPS
4. Helmet with +4/6 gem levels. 8% DPS and survivability
5. Unnatural Selection jewel. 7 Div, 8% DPS
6. Militant Faith, Forbidden Flame/Flesh package. 70 Div, ~20% DPS (hard to calculate)
7. Awakened Spell Echo. 12 Div, 8% DPS
8. Boots w/ Tailwind etc. ? Div, 8% DPS
9. Impossible Escape (Supreme Ego). 41 Div, 3% DPS and more Res Efficiency
10. Assorted alt quality gem swaps. 2-4 Div each, 1-2% DPS each.
11. Enlighten lvl4. 12 Div. Assists with aura balance and adding Haste.

There are so many moving parts, and I'm trying to make sure I haven't missed some critical piece.

Any input or tips on balancing the build are appreciated.

Just upgraded weapon and dropped Precision, so there's an empty socket in the chest aura set.
