loading similar components in main and custom HAL files

can you load a component(specifically a scale component) and use it in the main hal file, then load a separate component that is the same type into the custom hal file? I tried doing this and get an error saying "scale.ko: File Exists"

Not sure if it works but using "twopass" might help:
