You don't need to delete Create Object, you can modify it to work with Wii U.
Find this line in CreateObject.cs:
#if !(UNITY_FLASH || UNITY_NACL || UNITY_METRO || UNITY_WP8)
And replace it with this:
#if !(UNITY_FLASH || UNITY_NACL || UNITY_METRO || UNITY_WP8 || UNITY_WIIU)
A lot of actions have this kind of conditional compilation when Unity doesn't support a feature on all platforms. So it's always good to look for it in the source code to see if you can add your platform to the list. We add new platforms with updates (e.g. Wii U is in 1.8.0), but it's good to know how to do it yourself so you don't have to wait on us...
EDIT: Looking at the files in the Unity Playstation Mobile patch should give you a good idea of the files you'd need to add UNITY_WIIU to:
