I worked for a company that produced a software-controlled radio base-station. You have to know the secret to these devices: they can't actually cover more than 10 MHz at a time. There is a 10 MHz (or maybe a little better) band-width Yig that can be set in software to any given frequency between say 100 MHz and 6 GHz. This Yig limits sending and receiving channels to within 10 MHz of each other. Since Wifi channels are about 20 MHz each, your use case is not feasible. You could only use one channel at a time.
Now with more Yigs, you can use multiple channels at a time, but you are limited by the hardware. Yigs are very much not cheap, last I knew. A $300 software radio that can compete reasonable well with a Motorolla $5000 radio.... probably isn't running more than 1 Yig.
