Why do you say this? Surely if an alien species turned up and needed quick adaptation for their future offspring, then engineering-in native genetic adaptations in-vitro to their own genes that they knew to bring intellect and sentient capacity would be the way to do it.
You're suggesting that they'd modify their own genomes (assuming they were biologically similar enough for this to even be possible) until they were 98% genetically identical to chimpanzees? There wouldn't be much left that's alien if they did. No motivation.
