I'd like to see the capacity to upgrade our sciencey girls, from brainers to scientists, with however many steps in between as we're willing to add. Brainers are smart, but not actually trained, while scientists are well trained and smart and expensive as well. Getting new girls through the black market would always get you brainers, training them would be your job, for lack of a better location, the workshop would be a good place for it, though how runts would be involved boggles the mind.
On the subject of the runts, they could be upgraded too, a runt is supposed to be basically cheap labor, inexpensive, but in serious need of oversight and very clear instructions, with a little bit of schooling, they could be trained labor, and with more they could be true engineers.
I figure having an upgraded worker, science or workshop, would provide a bonus, even if the others in the project are the most basic type, one scientist/engineer could provide enough authority and direction to be noticeable, at least.
