Pathfinder Deadly Agility and Agile stacking for High dmg with good dex?

Not sure if this is the right area to ask this in but would the combat feat Deadly agility ( Deadly Agility (Combat) – d20PFSRD ) and the weapon enhancement agile ( Agile – d20PFSRD ) stack, like would i be able to get 2 times my DEX modifier to dmg because that would be really good for my 9th lvl hunter (since I do dual wielding with 4-5 attk's and a base of a +7 DEX and up to a +9 DEX)

This is probably off topic for this forum.  I think they do the exact same thing, so would not stack.  Probably best to check on the Paizo forums.
