No imagination required. Store and forward is slow, wasteful,
inefficient, disgusting, but cheap.

Yes. Some of the mesh wireless network vendors offer dual radios.
See:

Note that Belair offers a dual band solution, where the 2nd radio is
on 5.8GHz.

The leader is currently Tropos which finally produced a similar dual
radio, dual band product:

If you want to jump in with both feet, I suggest you first read the
research papers from MIT Roofnet mesh network to see how a working
mesh network scales and acts. There were quite a few suprises for me.

>If so, could a recommendation be made for a dual radio AP?
No, I can't. I try not to make recommendations without knowing what
you're trying to accomplish, what you have to work with, and what
environment you're trying to deploy it. I also like to recommend
stuff that I've played with. So far, I've only tinkered with Wi-Fi
mesh and don't like any of the systems that I've seen. Mesh networks
are not a universal solution to all problems and do not really replace
the backhaul.
