Static IP on wired and wireless adapter simultaneously

I want 2 static IP's, one for my wired and one for my wireless, and they connect through the same gateway (although I am not using them simultaneously). I use the following:
Wired:
10.0.0.4
255.255.255.0
10.0.0.1

Wireless:
10.0.0.5
255.255.255.0
10.0.0.1

If I try to change it from the ipv4 screen I get the attached error pop up screen, but if I change it through the advanced screen, I don't get the error but it automatically deletes the gateway from my other adapter! The big issue is, if I don't have the gateway in the adapter settings, I get an "Unidentified Network" in my "Network Connections" page and I cannot connect to the internet using the adapter that does not have the gateway.

I have searched every forum but have not found any resolution. Is this error just a false warning and not an error since I don't have multiple gateways? Maybe Win 7, by default, just throws that screen up if it detects 2 NIC's with an entry in the "Default Gateway" but doesn't really compare the 2 entries. Does Win 7 not see that UI have entered the same IP in both fields or does it just say "WHOA, you already have a Gateway entered in another adapter, I am not sure what that IP address is, but be careful because you shouldn't have multiple Gateways on the same network." Or is it saying "STOP, I will not function properly if you have 2 Gateways, even if they are the same IP."

The IP address for the NIC's are different, the IP for the GATEWAY is the only thing that is the same (10.0.0.1) and that is where the conflict is arising.
