I recommend being Strength-focused and prestige into Sanguine Angel to pick up Furious Huntress. Combined with an adaptive Orc hornbow, you will use Strength for to-hit and damage. For the archetypes, I prefer Sohei as it allows you to use Rapid Shot and Manyshot with your flurry. After you get your 2nd off-hand attack at 8th level (or 11th if your DM is nice enough to allow Sohei on Unchained Monk) I would go for 6 levels in Slayer to pick up Manyshot without having the prerequisite Dex. Important notes include the necessity of Heavy Armor proficiency for Sanguine Angel. I recommend a level in Warpriest for this (and eventually a 2nd level to pick up the Fervor ability). Also, Sohei can flurry in light armor - mithral breastplate is going to be your best bet if you focus on strength and let wisdom take a back seat.
As far as Zen Archer goes, I have only used it as a 1-level dip to pick up Precise Shot and Wis bonus to AC as a Wildblooded (Empyreal) Sorcerer. The ability to shoot around corners does sound pretty neat though. Just not sure how to target an enemy you can't see.
