Assuming it's still there, I am all for it.
It would provide a great deal of cohesion.
1. The advancement/transition of the tech and how the leaper's lifetime restriction was lifted.
2. With at least Janis along if not Beth and Donna as well, we could get insight into the original project's fall and the emotional impact of Sam's disappearance on the original team and their loved ones other than the vague mentions of Al spiraling into an obsession that consumed him until his final breath.
With strong writing, it wouldn't require an entire actual scene of someone exploring the ruins of the site, it could be presented in the form of a character, perhaps Janis or Beth describing it, the site itself, their personal experience with the project and name-dropping characters such as Donna, Tina and Gooshi.
Perhaps Janis had to visit the site to gather the tech and/or blueprints that enabled her to recreate the original imaging chamber which she used to briefly contact Ben and she could describe that.
Just as we got a little bit of insight into Magic's experience as a leapee of Sam's, I would adore a conversation in which Beth discusses her thoughts and feelings about Sam having saved her marriage to Al, how that impacted the first "official" time she met Sam with Al and whether or not she is aware of the timeline we watched as viewers in which she had Al declared dead and married someone else.
Thus far the references to the original series have been well tied in and intriguing and there are several possibilities for more.
