Can I use a 6 conductor cable, same gauge as CTs, to extend 3 CTs (current output) per cable without interference?

I opted to mount my energy meter transformers and boards outside of the main electrical panel as there is not enough room, and it is hardly weatherproof. This may be ok for breakers but I doubt it is good for electronics that are not conformally coated.

The plan is to run a 3/4 conduit between the electrical panel and my enclosure however this may make it a bit tight to run 12 CT clamp wires, plus 4 conductors for the 2 split phases (could reduce to 3 if needed). One option I am considering is to extend the CT wires with a 6 conductor cable of the same gauge. This means that each cable run can handle 3 CTs so I will only need 4.

The CTs are all current output so, as far as I know, they should be immune to interference between each other. The extension cables will be really short as can be deduced by the picture below (no conduit yet as I am still working that part out).

I'd like to confirm that I will not have interference issues between CTs if I use a single 6 conductor cable to extend 3 CTs (current output only) per cable. Has anyone done it successfully?

For clarity: I would not do this for CTs that have a voltage output.
