Summing op-amp 10 meters long

I’ve a linear sensor array (broadside).  The array is 10m long and it contains 20 sensors.  There’s a limit on the number of wires.  I can have a handful of wires running the length of the array, but can’t have an individual wire going to each sensor.

I need to sum the signals form the sensors.  For the purposes of this question, I’d like to sum in analog.  Could a summing op-amp with a 10m long summing node work for this purpose?

The bandwidth of the signal is under 1 kHz, if that matters.
