I'd suggest to change the plot to something that doesnt involve going into Tau 117, maybe exchange it to some hardcore research on the alien gate with the intention to jump through?
The NPCs in 117 would likely make you unhappy if present, as they are rather good in showing you that its a heavily guarded system
I would strongly suggest to keep the event on the Coronado side of the gate, everything else might turn out to be unfunny for non-Wilds.
