I appreciate the neatness of the Unity idea, but it isn't being used effectively. The only changes one sees are in minor dialogue options and the elements of the main mission. The team could have created a cascaded impact of changes across the galaxy.
Even slight changes could drastically alter the experience.
For instance,

1. Andreja could be the one leading the constellation, not as a destroyer, but as someone who gave them a unique direction. The lodge's aesthetics could become more... Varunn-centric.
2. The Crimson fleet mission could experience a role reversal. Imagine Delgado as a UC System head, with Naeva as his second in command. Their nature won't change. They may be brutal, but they could be all about fanatical justice.
3. Even some faction quests could be removed entirely, like the UC Vanguard, which may not exist in the new universe; only the Freestar Collective does. Imagine New Atlantis having a more rugged look. Or if there is less budget, let us name Akila, New Atlantis. And the standard New Atlantis does not exist. The well could be above the surface here. Mods have shown that it can be done.
4. There could be a universe where everything wants to kill you. Think of how, in the lodge, you become a villain in one of the universes; this could expand to the entire galaxy. Every faction may try to kill you, leaving you to fend off alone in a cosmos where all see you as the ultimate villain. Piracy could be the only default way to survive, and the extra companions could become a band of misfits, often trying to save the galaxy that hates you.
5. There could even be a dead universe. You enter the lodge, and everyone is dead; only a message about the artifacts remains, stating that it is too late for the universe, but save the next. It could be about you choosing the microorganism option to deal with terrormorphs, but it mutated and swept across the galaxy. No people are in the galaxy, only crazed starborn hunting each other. It could become a gameplay of you farming quantum essence and gaining the ability to incrementally increase the impact of powers, nearly infinite times. It could be called, "Starborn everywhere universe." since Starborn are like vampires already, killing their own kind.
6. There could also be a universe where everyone is silent, and the only way to communicate with others is through a text box. A budget-friendly way to handle the changes.
7. Other than that, it would be cool to have some additional powers in new universes. Some could only have powers related to building and surviving. It means no grav dash or wave, just harnessing the elements.

These are me thinking out loud, but they could elevate the multiversal experience beyond the standard run-and-gun, fly-and-shoot, loot-and-sell, build-and-build gameplay. Also, before you say "Bethesda hasn't done it before." Remember that the concept of Multiverse is novel, so why limit onesself to old ideas.

We have all talked about needing a Star Born DLC. What if one comes, but accessible only on the new game plus?

You travel with your companions, and beset by the new faction as soon as you exit the first temple.

They know who you are, and start hunting you to either destroy you or make you join them.

Their base? An entire star system. They have their own civilization, with the artifact based technology as its foundation.

A civil war between them is brewing. One faction wants to guide the rest of of humanity and make them stronger while protecting them, and the other that wants to hoard all the tech and rule over the galaxy.

New missions. New politics. New armors (star born-themed). New ships? Customisable star born ships. And new companions even.

A new hub star system consisting of 2 space stations. Two planets. One for each faction.

It could have two hub worlds, with their own identities. New Atlantis, and Neon combination, but better, and a lot more futuristic.
A man can dream.
