I was thinking that there might be something simple that could be fixed by looking in the routing table for the gateway address (it usually ends in .1)

But now I'm doubting that what you want to do is even possible using broadcast messages. Unless you would be willing to change the network mask on all your network devices to 255.255.0.0, creating a much larger subnet and eliminating the router.
