My opinion currently is that if it is possible that Jack Dougherty took the West elevator down passing by Baker and Truly AND also Dorothy Garner, and the elevator not seen moving, that is it therefore EQUALLY possible that 1 or 2 shooters from the 6th floor could have done likewise.
Since Jack Dougherty 's elevator trip and subsequent apparent conversation with Eddie Piper is NOT confirmed by either Piper NOR by Troy West, then its EQUALLY possible that Troy West and Piper did not see a shooter or shooters upon reaching 1st floor on that same elevator.
The time of this descent by either Jack or the shooter(s) from 6th floor must have been only after Truly had looked up the shaft as late as 70 sec post shots, before he and Baker went up the staircase. Its possible the West elevator could have come down passing the 2nd floor landing in the 15 second interval of time Baker and Truly are engaged with Oswald in the 2nd floor lunchroom. However, the top of the elevator should have been visible when Truly/Baker leave lunchroom and cross past the shaft.
This leaves that the West elevator came down JUST AS Baker and Truly have ascended about half way up the 2nd floor staircase. The time therefore would be about 1 minute 50 sec post shots, when West elevator is passing by the 2nd floor landing, and it stops at about 2 min post shots on the 1st floor, as Baker and Truly go past the elevator shaft on the 3rd floor, thus not seeing or hearing elevator or cables moving, OR seeing top of elevator when they passed by the shaft on 2nd floor landing.
