A minor update is in place here:
The approach which was originally proposed by Musti did not turn out to be doable - unfortunately.

We are now looking at other solutions. RIOT-OS [1]  and 6lowpan came to mind.

Absolutely. But It might be good to have them speak on a different protocol and frequency.
Something like 6lowpan or zigbee.
