>>5257029No one says we can't use the old machine spirit from his previous knight (if it survived) in making the brand new one.
>>5256968>>5256815Well we know that to become an acillian or a princeps is reliant on willpower. Theoretically, while I doubt Talos can make humans that perfectly succeed every time, with such advanced knowledge of human neurology he could attempt to create a breed of humans or at least modify a class of them to be more likely to succeed by having a genetic predisposition to willpower.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4175917/We know in canon that willpower can be increased genetically by 40k by merit of the genestealer cults. The offspring of downtrodden serfs become even more fanatical and utterly devoted to the cause than Chaos cultists, who only rely on the supposed promise of power or a better life. In almost all the books genestealers cultists are portrayed as being altered to be fanatical at the genetic level, never giving up even at the hand of torture, because their brains have been hardwired to be incapable of despair and have unshakable belief in the "cause"
Talos could theoretically try to improve the chances of Princeps dynasties aspirants surviving through some neural adjustments, combined also with his own superior spiritual knowledge of how to tame machine spirits and become one with the machine. I'm sure he could write a book that actual Collegia students would find supremely useful as Guilliman's codexes of war.
It would be yet another thing to add to our to-do list which by my reckoning for us players is already well into the hundred. In character I imagine Talos own To-Do list reaches into the thousands of items on a daily basis. We're probably like the Emperor in that same regard, we can just forsee SO much to do but are so limited in our capacity to do it
