I think that the bigger obstacle is not lore itself, but premise of the game - sector is kinda falling apart. If the player could just get access to everything and fix every problem, it would make all the existing factions look like fools. I think that while not impossible, it shouldn't be something you can do just like that.
It's worth mentioning how inconceivable it is that the core is surrounded by so many habitable planets (requiring minimal if any terraforming) and that they can be colonized and populated by billions of people and fully industrialized in the span of less than two decades.
I could suspend my disbelief here if it was theoretically possible but economically impossible, yet I have done it with ease and the collective population of my faction outnumbers that of every other faction combined at least 10:1. This isn't even biologically possible given the relatively long reproductive cycles of humans, unless you dedicate half of each planet to mass-cloning facilities. If it was this easy or even remotely practical, nearly every habitable planet and most resource-rich planets would have been colonized by the sector powers long before you showed up.
Furthermore, even if you completely ignore the colonization aspect, I find it impossible that you're pretty much the only one going around exploring the outer sector (excepting a few independent fleets). Given the relative abundance of blueprints found all over the sector, something that wouldn't be lost on any of the factions in-game, it makes no sense that A. they haven't been picked clean long before you showed up and B. the existing powers (minus ludds and pathers) aren't already utilizing those blueprints (except for what they had pre-collapse), especially the Hegemony who definitely have the manpower and ships to spare for mass-exploration.
And lastly, you the player are a god even if you play on ironman mode. You're the smartest, most powerful admiral in the sector and within a few years you can amass an armada that can crush even Chicomoztoc with ease.
What I'm trying to say is that this game is a game. The lore exists to supplement the gameplay by setting the stage and suspending disbelief somewhat, not the other way around. Perhaps reverse-engineering conflicts with the lore somewhat, but then again it would be far from the most lore-breaking and logic-breaking thing the game allows you to do.
