I almost always play with spire civilian leaders on. Until recently I was not aware that merely popping an AI Command would stop progress. I was under the assumption that I had to colonize that planet and keep it alive, or assassinate it outright. I usually captured one or two, and had the rest die in Cross Planet Attacks
Thus, 10 AIP/hour sounds ... fairly reasonable on 7/7, or at least manageable. 100 or 150 AIP isn't going to end a game outright, depending on your AI partners. Double that sounds a bit crazy.
Given how you want to think about your economy and avoid refleeting as much, I think giving you a huge resource bonus defeats the whole purpose.
Therefore I have a few brainstorms for you, but not coming from the perspective of high auto AIP games, so much as the resource management and refleeting perspective.
Go with a low cap game. Individual units are more expensive, and so having a dozen engineers suddenly assisting the wrong build queue can wreck your economy.
(If not playing with champions) Enable "Engineers do not assist queues." Then manually assign a set of engineers to each stardock/starship factory. Barring the occasional rebuilding fortress or totally murdered turret ball, your economy becomes a lot more predictable, even with fallen spire campaign. As well reinforcements will be produced at a less than fantastic rate, so you'll be a pulling back sooner rather than loosing the entire group and waiting and waiting and waiting for it to rebuild. If you ARE playing with champions, this will prevent engineers from automatically rebuilding the modules.
Set game speed to Epic (do not combine with 20+ AIP/hour). The simple fact that things will take longer should cause you to be less reckless... or become incredibly frustrated as you rebuild your entire fleet from scratch.
Set game speed to Fast, and combine with 20+ AIP/hour. You'll probably suffer more losses and rebuilds than in an epic game, but you should have the opportunity to keep up with the ticking time bomb.
Just some random thoughts. After I finish with my gravity drill/hybrid hive game I'll probably try some of these suggestions on as close to a "Vanilla", no-expansion game of AI War. Right now, I haven't played a fast or epic game in a long while, so I could be off base
