Adding a tech tree for people working in staff positions would help incentivize players to play these factions more often, give the factions direction and purpose when nothing else is currently happening, and allow them to ramp in power similar to everyone else in the sector. Currently, Colossus Central and Medical Dispatch staff are the only faction to not have their own tech tree. Even the factionless mercenaries have the USSP tech tree for themselves. These additions seems like a natural next step, and a somewhat necessary development in order for staff positions, CC staff especially, to stay relevant much later into a round.
While I think any sort of tech tree would be better than the nothing they have now, I do have some suggestions for direction if that's what's missing for something like this to be added. Perhaps the CC tech tree would be more focused on lasers and less lethal options to help with dealing with chimera infestations and bandits, the two things CC Judges will most often be dealing with, and it allows CC to fill a niche no other faction currently fills. Disabler tech seems like a good choice especially since currently no one really uses it, which results in people taking traits like lethargic with little to no consequence practically ever. some branches to help with other CC jobs, like mailmen janitors and valets getting tech to help with tracking people in space, cleaning and maintaining ships and stations, and providing some form of service and assistance would also be cool, since they're part of the CC team as well and should get some representation. Some medical technology to help with the recovering and reconstructing of the dead would be cool for MD as well, maybe a way to research cloning technology later into the shift.
Again, this doesn't have to be the route taken for the tech tree. As long as something gets added it would be a large benefit. As is, hardly anyone plays CC staff and I truly believe it's for this reason especially.
