Not reborn HoL, 'Great Rebellion.' That's a T/V rebellion.
You know, I actually think that the Procyon Confederal Autonomy is the only joined Terran-Vasudan rebellion in any campaign so far. It's either a plain Vasudan rebellion or a pure Terran rebellion. A joined rebellion versus a joined alliance makes it seem as though the Terrans and Vasudans are much closer.
I had an Inferno idea in which the GTVA is poised for another T-V War, but then a huge rebellion that is against a second war comes up, working together. The player overthrows the main GTVA government here. A new government is set up in which the Terrans and Vasudans are equal, etc. etc.
