if you would create a bridge interface between the lan en the wireless interface and do this on every router, you can do this.
no prob.
but i would recommend this solution, as you are bridging, all broadcast traffic is passing your bridges.
i would recommend, to use routing.
for example.
router - lan MT
10.0.0.1/30 - 10.0.0.2/30
then config this
wifi 10.0.1.1/24
and put a route in your router 10.0.0.0/30 —> 10.0.0.2
this way you don’t use nat on the MT only on the router… and you still have seperate subnets with it’s broadcast traffic in each segment.
