Can Vicious Stomp be used to Disarm or Sunder?

[MacGurcules]

Vicious Stomp grants an attack of opportunity but requires that be taken with an unarmed strike. Disarm and Sunder (and Trip, but that shouldn't apply here) are performed with a weapon in place of an attack.

So as long as the weapon you use to perform the maneuver is an unarmed strike, could you attempt a Disarm or Sunder using the Vicious Stomp AoO?

[Kazaan]

I suppose so, so long as you only apply your applicable unarmed strike bonuses to your roll. So basically, you trip someone to knock them prone, then as they're falling you kick their weapon out of their hand or, alternatively, kick it into pieces. Seems legit.

[Quandary]

yes, the same would seem possible for other 'free' CMB checks, e.g. Wolf Trip or Grab attacks...
they are still 'attacks', so you can make any CMB that can be made in place of any 'attack'.
(sunder used to be only with attack action, paizo has changed that, at least by FAQ so far)

[Kazaan]

Any melee attack, mind you. You still can't disarm or sunder via ranged weapon except through special ability.
