Why have we not seen any Aiel Asha’man?
The Aiel have a different tradition, as I have mentioned in the books. When a young Aiel man learns that he is beginning to channel, or thinks that he is, that is taken as sign that he has been marked out to try to kill the Dark One, and he sets out for the Blight in an attempt to do so. And given that any Black Tower recruiting party that showed up in the Waste would very likely find itself in a fight to the death fairly soon after arrival, it isn’t a spot that anyone would pick for recruiting. Now, it may be that some Aiel may finally join the Asha’man (I’m not saying they will!) but traditions are hard to change, especially when they have religious overtones and have lasted a few thousand years.
