It is very rare, but I've seen some companies using a coaxial cable, which is suitable for interconnects because of its inherent shielding capabilities, for a speaker cable design.
I have not seen anybody using larger gauge cables (usually used in speaker cables) for an interconnect design. It is generally not recommended to use speaker cable for interconnect and vice-versa.
You can contact CRL and ask them if that particular cable design can be used for an interconnect cable. I will be very surprised if CRL says yes to this question.
These are two interesting articles on audio cables:
