The AIC mod may interest you; it can be downloaded from
here. The mod takes a rather different approach than TDM: where TDM focuses on better scripts for the AI, AIC gives direct assets to the AI to compensate for the things the AI does not use well (remote mining for example).
AIC is also based on the Proportions mod, so you should expect a slower pace, and fewer planets/ships to manage. Population plays a more important part, but you have the option of skipping the "moving population around" part if you want.
