Its not possible, we need independent radio chains to do that. Its more of a
protocol thing, where AP needs to available all the times so switching
is not an option, where as in STA case we can do that its called
Multi channel Concurrency using a single radio as you suggested.

But i doubt that feature is part of mac80211-ath6kl combo?
