Specialist ideas: temporary buffs from specialists

So I have been thinking a bit about specialists again. So I was thinking about specialists that provide a big temporary boost and then after a period of time fall back onto a lesser ability. Here are a few I came up with.
Propagandist
After you hire the propogandist chose a factory in your radar range. That factory does not produce drillers for 3 production cycles. after 24 hours that factory gets -5 to its shields.
Prospector
Adds 20 to your neptunium when hired. When attacking a mine he destroys 5 drillers
