Normally the config you describe should be supported with the new MIC metric.

Even if you have multiple channels and the fastest path is changing
channel at each hop, OLSR keeps routing packets on the same channel.

MIC should be based on the SNR value, and I hope someone is working to
get this value out in user space for most radio chipsets. This is not
easy, especially when ad-hoc implementations are clumsy for most
drivers. SNR values have to be displayed per neighboor in ad-hoc also.
