ESC and twisted pair

Using arduino topside.

I am looking to use the BR teather.

1 twisted pair for my video
the other 3 to be spread across my 3 ESC’s.

That does not leave me with a control wire for my lights.

So, does each twisted pair need to have ground running all the way back up?

Or can I use:

BRN - ESC 1
BRN/White - ESC 2
BLU - ESC 3
BLU/WHT - EMPTY
ORG - Video Data
ORG/ White - GND
GRN- LED
GRN/WHT - EMPTY

Second cable will carry power down from topside battery. No power onboard ROV.

Will the ESC’s be okay with this?
