Analysis based on taking the stat weights, assigning all the gear their values, then finding what [non-acc] -> [acc] gear slots lost the least value per point of acc gained. That item spread should land at 466 acc. I don't have info on how materia fits into the HQ crafted though. That may impact the Ring, in addition to the option of adding Vitality to the ring which could be useful as a separate option.

Edit: Stats taken from xivdb.

Edit2: Most of the slots were close. The only outliers were the Belt (get the Myth belt over Allagan for sure) and the Bracelet (use Allagan / buy Myth last). Boots also leaned towards Allagan a moderate amount.
Does this take into account the head slots? I know the mythology one has a stupid amount of accuracy
