Additional research and power modules

[MIH-XTC]

What about requiring a 2nd research and power module to unlock the last 3 power and research upgrades (gas turbine + neural) and increase their outputs. It would require players to upgrade their research/power structures a second time and also give the structures a new appearance. We can make it somewhat costly to make it a strategical decision. Good idea or just an unnecessary distraction? You decide, just throwing it out there.
