Get rid of the wired router. Connect a 10/100 switch to the wireless router and connect all your wired devices to that. Configure them to use 10.0.0.x IP addresses and the subnet mask 255.255.255.192. Set the gateway to 192.168.1.2 and manually add as many DNS servers as you want.

I think this procedure should give you the result you want, although I still don't understand why you want it.
