Recorded seperate samples for each test location, and then wrote visualization software that recombined those recorded traces.

Because there is no real reason for two different runs to be significantly different, (especially if the electronic switch shorts out the source ends of the wires between each test to discharge any capacitance that built up between the wires), the results should not be much different than if using an 80 channel scope.

Except the battery will get run down over time, and won't produce the same voltage at the same speed for the 80th run as it does for the first. You need a benchtop power supply for that.
