So, based on your ideas, I've constructed the timeline in my head for you to review:

-The Qyaari on Lehon get into the Temple by way of Yerbol and Aria channeling the Force through the strength of their bond, seeing as Revan AND Meetra would know a thing or two about bonds and would want to lock whatever secrets are still in the temple from Force users who don't understand how powerful a tool the Force can be(more on that I suppose when they meet Revan and Meetra). 

-All other doors are locked, however, except for a singular path that leads them up to the roof of the temple where Revan and Bastila fought each other AND, if I remember correctly, has a terminal that can broadcast communication signals (right? That was up there? I'm pretty sure there was a terminal up there and I remember thinking to myself how did the Rakata install such a fancy looking piece of equipment on their ancient temple back in the Infinite empire days?)

-There they update Neta and the Council as well as upload the star map data to Vano, who needs time to crack the maps(obviously). This would be a good point for a Bioware-esque "interlude" where characters get to talk to each other. The interlude can happen on Alderaan and considering that our characters really haven't had a true interlude like in the past acts, I think they'll need one here. I mean, Voldon died, what, a week ago in our current timeline? Ari and Yerbol barely had time to talk then and now I think these two need to have some serious discussion before venturing out into the unknown. I've also got some scenes ready for Neta and Ethan. If you want Ari to participate in either of their sequences, let me know :) 

-From there...well, back into the unknown. Goodness, doesn't this feel like we're almost starting a new thread entirely? I mean, this'll be an entirely new universe. We've only really dealt with the fringes of wild space, but this...this is going to be crazy stuff. 

Edit: Do you think Kira coming would be too much? I'm struggling with the idea of bringing her or not, but I feel like it would be a very Kira-like thing to do to show up and force her way onto the expedition because she feels like she needs to leave the known galaxy for a long time(for obvious reasons)
