True maintenance costs for facilities would also have to be hardcoded, but it might be possible for the research and intel facilities to generate negative resources each turn without a hardcode change. If the game engine will accept negative values for those abilities as it does for others. I have never tried it. It would take some tweaking to get the numbers right, but that would reflect ongoing costs of research and intel, beyond just building of the buildings.
