I personally have no idea, sorry. I haven't tried doing it so I don't 
know if it's possible. 

You could test for yourself though - you just need to hack up ath9k to override: 

* when queuing a set of aggregate frames to the hardware, override the 
TX descriptor ACK setting (ie, forcibly disable ACK in the TX 
descriptor when it's an aggregate); 
* always treat sub-frames as "ACKed" when handling an aggregate TX 
completion (as if it did work, the BA bitmap is likely to be all 
0's..)
