1. Is it even close enough for that to be remotely viable?
2. Archeotech smarceo tech that shit's gonna be corrupted as hell.
3. Dude where's my time, you don't build up a sector sized polity in anything resembling a speedy manner especially when
4. Ophelia is absolutely going to have plenty of forces coming in to take the remains of the storm. They're vastly larger than callmaus, are significantly faster, have more than enough resources to send out either a colonisation fleet or a destruction fleet and have a religious imperative from their god either to hide the evidence or colonise it to turn into a giant temple. If the guy even gets there he's going to be a major late comer simply due to be slower.
In all honesty, the entire venture seems like something Akadia cooked up to kill off an unrepentant, overly ambitious nob head in a way that the conservatives couldn't bitch about given how unlikely it is they'll find anything the even lower chances that anything found won't make them become Tjapan and the enormously high chance of being slammed by Ophelian pope fleets.
Not gonna get into a drag-out argument over this, so I'll just say I'll disagree and that you're wrong about a multitude of things. I will, however, go over one of your wrong-sayings because it gives me an excuse to educate on the nature and nuances of one of the galaxy's major polities.

Callamus' politics isn't the same as the Trust's. You don't have the Progressive-Conservative split where one side believes that science is heresy and you must burn the unbelievers. What you have instead are the Novus and the Old Guard. While analogous to the Progressives and Conservatives, respectively, they differ from their Trust counterparts in rather important ways.
In brief, the Novus believe in technological growth via innovation while the Old Guard believe in the weakness of flesh and technological growth via discovery. Already we see a difference, if a minor one. Their opinions on flesh is in contention with the Organicists faction, not the Novus, who are ideologically indifferent in this matter. The Conservatives-Progressives split had nothing to do with the strength or frailty of flesh.
The big difference between the Old Guard and the Conservatives is what they think of innovation. Conservatives believe that innovation is heresy. The Old Guard merely regard it as foolish and inefficient, similar to how the mainstream Mechanicus in 40k think that Explorators are foolish and dumb for spending so much on rumours of technological scraps, though they by no means see Explorators as heretical or their results invalid. (In this regard, the Old Guard are actually pretty deviant to classic Mechanicus, being a faction that loves Exploratoring.) A Conservative will look at innovation and cry "Heresy!" and smash new tech, while an Old Guard will look at innovation and say "Your experiments are eating so many resources can you please do something useful" but accept any new, proven tech that comes out. (Though they may not hold the new tech in as high regard as old tech.)
The difference between the Novus and the Progressives is subtler but just as present. In short, the Progressives believe in what we would call the scientific method while the Novus...don't. A Novus and a Progressive both invent a new, heavier capacitor for a specific lasgun pattern but find it somehow makes it lighter; the Progressive will try to figure out the base principles of how that works while the Novus will declare he's found a holy synergy between the two machine spirits and move on to the next experiment.
In short, Progressives vs Conservatives is an argument over whether or not it's heresy to break from the strictures and laws of the old Mechanicus. Novus vs Old Guard is about the practicality/idiocy of spending loads of resources on one specific method of getting new tech over another, never increasing the Forge-Empire's fundamental knowledge or understanding either way.
While I'm here, your assessment of Lethe's motives cannot be right. In the debate of whether Old Guard is more practical than Novus or vice-versa, Old Guard has basically won. Everyone at the Grand Conclave did innovation, so Novus received validation, but nowhere
near as much as Old Guard, because there was
way more tech that was acquired through STCs and archaeotech. The Fabricator-General of Callamus is absolutely not gonna go "Even with this planetload of empirical evidence that the Old Guard are correct, I'm going to think they're full of shit and try to get them killed." She's sending an Explorator fleet to the Storms of Judgement because it's what the Old Guard want and the Old Guard have proven themselves to be very wise.
