If you try the scheme that your are thinking of doing, your probably going to freak out your router, because you will be having arps with the same MAC address coming from both subnets. It would be interesting to try it and see what happens, though. What I'd suggest that you do is move to using a class B address with a standard class B subnet mask of 255.255.0.0 If you have that many clients, you should be able to obtain a class B from your provider.
