Idea for a Saturn Raid mission

[murekemursujokapieras]

We've never actually seen Saturn, currently we only got one captura scene and it's of the Saturn Six prison.
In the lore Saturn is described as far more than a hiding place for a prison though, as it is the Grineer's strongest foothold, even being said that it is nigh impossible to overtake. So it really sounds like the perfect place for a Raid mission if those actually come back. Something like the Tenno taking over a Grineer military base having to fight against a very large amount of Grineer and then the leader of that base, and this could maybe even be just one part of a bigger mission, where you'd go for the head of all military operations on Saturn.
I think it'd even be possible for Saturn to include things or characters we haven't met in the game, like Dr.Tengus and his Grustrag Reconditioning facility, since their locations haven't been mentioned, but it'd make sense for them to be in one of the most guarded areas.
