Looks like there is a Touring the Stars for Hall that came out after the end of the dynasty I would have included

There is also an Star League era planet called Brownsville that was helped with the same tech that Kressly is making to restore Bryant, Telos IV and others and it was believed no one lives there anymore we could check out and see what happens, and there was a Touring the Stars for it.
Touring the Stars: Brownsville - BattleTechWiki
It's in our borders, and I would have brought Brownsville back into the Inner Sphere and done a campaign there.
Here is it's location in 3067 -
See how it's right next to EE, Capolla, Terra Firma, and Liberty?
Also, see where Ruchbah is right next door to us in Ingress and Fletcher?
See the abandoned worlds of Bex, New Stephens, Mandal and Hechnar in our borders? They were also Star League era worlds that disappeared, I might have added expeditions to them as well after the Brownsville one. We don't know anything about them.
