In that case, it would be possible to increase throughput with a bond interface. It may be that ifenslave-ing ath0 and ath1 to a mode 0 kernel bonding device at both ends would do it, but it depends how the interface is set up, and what is between the two gateways. Point-to-point it should be fine; if it needs to be routed then some sort of tunneling devices would be needed. Setting that up isn't really a Shorewall question, though...
