I don't see playing as an industrial race as not playing to our B-Caste heritage, merely as recognizing that sometimes you shouldn't reinvent the wheel (especially when the wheel in this case comes from a CAD database).
Using and concentrating are different things...
Look at mining, we went with adapting ourself for that, not boosting some tech drone and developing mining equipment like tech queen would do
Same goes with fertilize t-drone and "put all jelly to get tech queen" route. That's just turning off our chances to upgrade Kai in exchange for ability to improve tech somewhat faster
I think we just need to assimilate production and techs of bipeds, but for that we need to win some battles first
Which is also why the Scouts should not travel as a group or attempt to 'fight it out'. We don't need the extra 'excitement' in the Hive quite yet.
Then why scout at all? Why arming the scouts? One group studying a single target is less likely to be discovered than 3 scouts scouting different targets
And if discovered, group of three scouts have much higher chances to kill the enemy before they spread the word
Also, group of three is less likely to die and leave corpse and piece of our technology for humans

As for hybrid flower, I tend to abandon it... My idea was to create a flower for nomad Kai hives, it's obviously unsuited for that role unless we spend huge amount of effort that would be better put elsewhere. Like making queen flower producing more jelly, or creating plants that can grow in tunnels with minimal tending
Our R&D resources are limited, let's try everything route is just bad
