Okay, I got two questions that almost sound the same.
If I had the Combat Reflexes feat, could I attach Stunning Fist to the Snake Fang style feat?
Moreover, could I use the Kata Master's (Swashbuckler's) Opportune Parry and Riposte to parry an attack and interject with Snake Fang instead of using the normal riposte?
Edit: Can you use two AoO's to link feats that use AoO's?
You can already use Stunning Fist with Snake Fang. Stunning Fist is a "not an action" that modifies an unarmed strike. There is no requirement for that unarmed attack to be taken on your own turn.
Stunning Fist has a once-per-round limitation, that is, once from the start of your turn until the start of your next turn. Combat Reflexes doesn't do anything that would change that.

While using the Snake Style feat, when an opponent’s attack misses you, you can make an unarmed strike against that opponent as an attack of opportunity. If this attack of opportunity hits, you can spend an immediate action to make another unarmed strike against the same opponent.
Opportune Parry and Riposte makes the attack automatically miss. That triggers Snake Fang, if you have any AoO remaining (such as from Combat Reflexes and 12+ Dex). So you can parry; riposte; and make an AOO from Snake Fang, OR you can parry; make an AOO from Snake Fang; and make an immediate action attack from Snake Fang. You can't Riposte and make the 2. snake fang attack because they're both immediate actions.
Oh right, my apologies. I must have been thinking about my second question when I was writing that. But thank you for answering my questions.
But could I still use the AoO granted by Crane Riposte to do Snake Fang?
