After a little bit of, erm, "optimized playing" I was able to get all the rewards and, although some of them are kinda OP, the amount of time it would take to get them legitimately and leveling the institute to get them where they actually are better than the vanilla offerings is more than enough to get godlike the usual way, i.e., playing normally and optimizing your fleet. If you're going to balance to get it a little more vanilla-like, I'd like to request you make a version keeping the numbers the way they are. I really enjoyed the leveling aspect, and it gave me a reason not to avoid the Starlight Cabal and their goddamned Hyperions like the plague.
The descriptions are also top notch.
