So looked further in game at Feats,
Power Attacks seems out as it says "melee" in description.
Stunning Blow Still sounds possible.
Many Shot seems out as it refers to shooting arrows, though I still want to test it to be certain.
Rapid Reload also seems out as it states repeaters specifically.
Also have access to a Halfling Rogue and discovered that while it has weapon focus for all of the thrown weapons, I would still need to use an additional feeat to use axes/hammers/shurikens.
Marcus-Hawkeye, I would still like your input when you have the opportunity.
