Genetarr should carry over, but as "memories", being not as strong as the original. 25% attack loss and improved influence lasts half as long?
Imo the biologist should be semi automatic, like a trap, but i can see that being too OP. Half planet pop restored AND THEN 25% max population for 1 hour, cooldown 12 hours sounds less OP and more safe

Raider is totally fine, and keep the raiding bonus + your suggested abilities or lower it to 20% raiding bonus
Physicist could sorta be like biologist+have chaostatic inhibitor due to their knowledge of energy fields.... so restore half shields AND THEN +increase max shields 50% for 2 hours, cooldown 6 hours? Idk what to do with the inhibitor, I would suggest doing it like Genetarr "memories" and have it as a weaker inhibitor, 100% shield regen stop for 2 hours or 50% shield regen stop for 4 hours (maybe a choice between those two >:D)
Maybe merchant still gets 20% moar cargo+ your suggested abilities? Great for noobs who don't know what mineral is when they first start.
