Tbh I have a bad feeling about this plan. Its hard enough to do it with 2 real people on each side. Ofc its up to you, how fast you can click stuff, but im pretty sure that I wouldnt be able to do it like this. :P Also starting with the ranged lever isnt a good idea. By the time you hit STR and WIS, the ranged lever will be back in its initial position.
For my test runs we were usually 3 manning the pre raid. It should be possible to 2 man it, if you have a pet. Its not only a matter of those north levers/runes but also the levers for the air jet at the end. You need 1 person on the pipe and atleast 2 ppl (or maybe 1 person with pet) to pull the levers below.
