Some questions about Corsairs sleeved cables for PSU

I recently bought a Corsair RM1000 Gold. My case (in signature) is kind of overcrowed and that makes cable management a bit messy since the cables that come along with the RM1000 is kind of stiff.
Been looking at the pre sleeved cable set like:

The 24-pin i can buy another color f:ex if i want to mix red/white but would it be possible to buy:

And throw in some of the white 8-pin, will the cables from the second kit fit in my 1000RM?

If not is there any way to buy loose sleeved cables, i have been looking around but cant find it.

Or if anyone here on the forum read this and are willing to trade some cables. PM!
