I was doing very similar math recently to figure out if I should actually pass on the coil boots or not, were they to drop. They didn't drop, but here's what I found anyway:

It is possible to get coil cap accuracy with the allagan boots and myth helm - but only barely.

Looked your gear up on lodestone. The answer will be jewelry mostly and food for the rest.
- Your earring has 0 accuracy currently. Get crafted for 12 accuracy, or allagan for 11 accuracy.
- Myth ring is 16 accuracy total, 5 or 7 more than current. Plus VIT/parry.
- 2nd ring could be crafted for 12 accuracy total, as well as str/det/crit upgrade. 3 more than Darklight.
- Neck could be crafted for 12 accuracy, or allagan for 11. 2 or 3 more than current.

I'd go for the crafted ear and myth ring immediately. That gets you 17 more accuracy assuming you ditch Hoplite ring. Two more crafted jewelries are worth 3 accuracy each. Add food and I think you're there.

Prices on crafted stuff are way down recently, at least on my server. Personally I like Rose Gold over Gryphonskin because it's cheaper to meld STR than VIT. Next patch should reduce the ingredients needed greatly as well according to SE posts. Look me up on Lodestone if want to see how I melded mine.
