You should just be able to inherit from DisplayNameAttribute and override the DisplayName property:

public class DisplayNameExAttribute : DisplayNameAttribute
{
    public override string DisplayName
    {
        get
        {
            // do what you want here.
            return base.DisplayName;
        }
    }
}

I haven't actually tried to implement this, so it is possible that the DisplayName attribute is coded such that some other extension point will have to be used, but I'll try to confirm.
