In theory the AI HW strategic reserve and mini-exos could be buffed, but at least the latter sounds like it basically performed to spec; took your superweapon to avoid death in that one case. Cheddar Shields to Full Power, Mr. Scott!
Cheese shields for the cheese cannon. I mean, an artillery golem? In the base game? I suppose I'm asking for it, but still. Though I could have just savescummed, as well.
As far as buffing 10/10, the main thing that sticks out to me is that it let you get away with too much hacking.
Too much hacking? That's crazy talk.
The CPAs are another obvious area to ratchet up the pain
Trust me, they were painful. Though instead of MOAR ships, fixing the carrier logic, and having them behave more intelligently (attacks everywhere iff lots of ways in, otherwise giant hammer). And above all, don't have them hang around on my wormholes. They don't last.
I also had Champion & Co. with the nemeses too afraid to attack my main choke, no other place to go, and a habit of waiting on the other side of my wormhole.
