Molex voltage mod

I want to take a molex extension cable and mod it to do only 5v. As far as my understanding goes all I have to do is switch the 12v wire with the 5v wire and cover or remove the 12v wire, but do I also need to remove one of the ground wires? Also I plan on daisy chaining 3 fans onto this so will this be safe?

 

Here's a diagram to help explain what I want to do:

Regular molex = (12v - G - G - 5v)

5v Molex mod = (5v - G - G - X)

 

The fans I'm using are 120mm CM Red LED Sickleflow's

 

Thanks :)
