[Suggestion] "Stages" Galactic War Mode

I am curious on making this a mod (might take something external to manage the save files), but wanted to pitch it officially nonetheless.

Suggestion is, a simple adding on to Galactic War, is if a player just loves his Galactic War ending loadout, let them click a "Next Star System" button, which generates a new system, but keeps both their loadout from last completed match, and generates enemies based on "turns" last match and building up from there (as if it were still generating enemies based on difficulty from where they left off last match)

You get exponentially harder enemies, but also to continue to hone in your loadout and get stronger and stronger.

The thing is, player can have all those cards wich can reduce cost of something, improve speed/damage and stuff.
And the only thing you can do with AI is add eco multiplier. So you can't make GW much more difficult, it will become impossible to win after certain point.

I was under the impression that the player cannot discover duplicate cards, the AI is also bound by a turn-by-turn simulated card-discovery tech system, as well as eco and difficulty of AI, and that eventually at worse case scenario the player would just be maxed with every tech and start getting a LOT of subcommanders.
