I'm too tired to try to process most of that right now. I'll just remark on a couple of your points. You have Adams and Styles at the stairwell 30 seconds after the shooting ended. In order to have them there that soon, you have to disregard Adams' time of 15 seconds of staying at the window. Barry Ernest said that she stood by that statement. The other thing is that Dorothy Garner never saw them go down the stairs. That being said, your scenario may work. As I said, I'm too tired to say with any certainty.

Victoria Adams talked to Barry Ernest 35 years after the event. I'm not sure how much value can be placed on a time estimate after all that time. But more importantly, Adams told the FBI on 11/24/63 that she and Styles went down the stairs
immediately after the last shot. She said something similar to Jim Leavelle on 02/07/64 and again to the FBI on 03/23/64 and she repeated it again in her testimony. And Sandra Styles told the FBI on 03/19/64 she and Adams left "at that time" after hearing the shots and seeing people running.
Having just read Victoria Adams' testimony again, she does say at some point that she left the window after "between 15 and 30 seconds, estimated, approximately, but she's hardly firm on the subject.
Secondly, I used as a guide, for the 30 seconds to get to the stairs, the time trial done by Discovery's "unsolved history"
In it, they timed "Oswald" as needing 27 seconds to get to the stairwell. I used 30 seconds just to be on the safe side. However, "Oswald" had to walk the distance of the building from the South East corner (the sniper's nest) to nearly the North West corner as boxes block his way for a short cut. He then had to turn left and walk from the East side of the building to the West side.
Adams and Styles, on the other hand, were situated in the middle between the East and West of the building with behind them a door that lead from the office space directly into the storage room behind it. The distance they had to walk was considerably less than "Oswald"
Mr. BELIN - Sometime after the third shot, and I don't want to get into the actual period of time yet, you went back into the stockroom which would be to the north of where your offices are located on the fourth floor, is that correct?
Miss ADAMS - Yes, sir; that's correct.
Mr. BELIN - When you got into the stockroom, where did you go?
Miss ADAMS - I went to the back stairs.
Mr. BELIN - Are there any other stairs that lead down from the fourth floor other than those back stairs in the rear of the stockroom?
Miss ADAMS - No, sir.
Mr. BELIN - Those stairs would be in the northwest comer of the building, is that correct?
Miss ADAMS - That's correct.
Mr. BELIN - You took those stairs. Were you walking or running as you went down the stairs?
Miss ADAMS - I was running. We were running.
In the Discovery video "Oswald" needs only 17 seconds to walk the distance of the building from South East to North East. Adams and Styles could walk in a straight line to the stairs, as the 4th floor storage space was empty (if I recall correctly), and thus would have only required some 17 seconds to get there. They could indeed easily have stayed at the window for a few seconds and still be at the entrance of the stairs 30 seconds after the last shot.
The other thing is that Dorothy Garner never saw them go down the stairs.Actually, we don't really know what Garner saw or not. The Stroud letter only tells us that;
"after miss Adams went downstairs she (miss Garner) saw mr Truly and the police man come up."Garner was with Adams and Styles at the window. When the girls went to the stairs she followed them from the office to the storage space. There is no reason to assume that she did not see them go down the stairs.
