Nutone to Nucleus - need electrical help!

My house was built in 2001 and has a NUTONE intercom system which I dearly hate.

I thought the cable run to the satellite intercoms was cat 5e but actually the cabling from each satellite intercom to the base station in my kitchen is proprietary nutone "IW-6 3PR 22AWG" cable. There are 3 twisted pairs (6 wires) - black/orange/red.

I want to install and power my Nucleus Anywhere intercom units using POE but ethernet cable is 4 twisted pairs and it looks like the power runs across all pairs and 4 pairs (8 wires) and 6 wires is not enough.

My base station in my kitchen is where all the satellite intercom cable runs to and there is AC wiring there so I could plug a POE switch in where the old NUTONE main box is.

Can anyone think of a way to send power through the Nutone IW-6 cables *safely* so I can power my Nucleus without having to pull wires?

Looks like MODE A/B (supported by the POE switch I purchased) only requires 4 wires.

The switch I bought to run POE says on the back:

"POWER PIN:
[black square] Mode-A /1,2(+)/3,6(-)
[open square] Mode-B /4,5(+)/7,8(-)
"

using https://en.wikipedia.org/wiki/Power_...hernet#Pinouts

it's 22g wire so should be safe to run POE through regardless if it's NUTONE cable or not correct?
