Change WoW.exe location.

What I want-

So I need to change the WoW.exe pathway. So I go into innersace configuration (right click icon, configuration), game config, world of warcraft and then I change the profile's .exe location. Apply and reload. So the game opens up with the new .exe (wow1.exe for example) however I get no isboxer overlay nor do the hotkeys work. What else do I need to change for it function correctly?

Why, TLDR.
Since we're all curious little monkeys.
I have to use a service (exitlag) that changes my ISP's routing on the fly to maintain low latency to US servers. It looks out for the WoW.exe process and re-routes. It doesn't work so good if all my clients use the service (multiple wow.exe) as it does chew a bit of data up.
