Talented Monk | Fighting Style Question

[Etruis]

One of the players in our Gestalt game is trying to run a natural weapon Monk/Ranger with Fighting Style it states.

"use abilities and attacks that normally work
with unarmed attacks, such as Stunning fist
and Punishing Kick, with these weapons).
The monk may also deal lethal or nonlethal
damage with any weapons in a group he
has selected without penalty."

I was wondering, if he could combo that to use his feat Rending Fury, with the Boar Style feat. He says with the Fighting style listed above it would allow him to use his natural attacks to be considered as unarmed strikes for activating Boar Styles special.

Seems legal to me.
You gain the rend with a feat, then you take a feat that reduce how many strike you need to rend...

Yes, the wording in the fury about natural attack can cause some arguments, but I believe it was wrote like this it's because rends were supposed to be paired with natural attacks. A dev comment would be handy to be 100% sure, but I'm confident it's at least RAI and should work.

I wouldn't even ask you to be monk to make it works.

Sidenote: Be aware your quote is only partial, it's confusing without the beginning.
