Skipping forward would be fine by me. We can do what we did for our six month time skip, inserting little memories and creating ones as we go. Also, it might be kinda cool for them to visit the sanctuary on Taris and meet up with some of the Council in order to let them know that they're heading after Renso. I would assume the Council would frown upon it initially, but would understand their reasons...somewhat xD(I'd assume they would want the duo to stay behind to help out) That would, of course, be followed up by a larger reunion on Zinuthra as you alluded to. 

Zinuthra would then naturally be the site for the new academy? Or at least, the makings of one. That way Force users can have a place to train. 

And actually, I don't know much about the Chiss myself, but methinks it would be kinda cool to explore their backstory. Maybe tie it into the True Sith? Cause the Chiss seem to have an attraction to the former Sith order, so why wouldn't their ancestors have the same...WAIT, WAIT. This may sound crappy, but I just got an idea: 

With the Renso about to die, he warns Aria and Yerbol about the Chiss forebears, who were once crushed into submission by the True Sith. The Chiss ancestors were wild, uncontrollable warriors that lusted for power and held a strict hierarchy that punished those who were ruled underneath it. Years of subjugation created a dependence for those scant Chiss survivors to cling to the True Sith for survival, said survivors working in secret to preserve whatever of their race they could in stasis chambers mainly used for Masters of the True Sith to meditate in. When the True Sith's realm collapsed, these pods were forgotten about until an Alliance expedition uncovers and awakens them. Rife with power, these Chiss ancestors begin to wreak havoc on the galaxy, attracting all sorts of unsavory characters to join their cause in "throwing the galaxy into total anarchy". 

What do you think?
