What I believe some IW may do if the heresy never happened and they were allowed to lay aside their duty as Astartes
Forrix - still a logistician, works very closely with navigator houses to maximize efficiency. Will translate lots of books on the side into the three dozen or so languages he knows enough of to do so. Writes (pretty good) existential fiction but no one has read it cause it's not good (enough). Likes to play strategy games and poker with worthy players; he's good at managing his money and emotions though so it's unlikely that he'll ever become a gambling addict.
Zakayo - Under Forrix' logistic net spanning prolly a galaxy arm. He likes being under Forrix (reliable, standable and not a bitch). Plays various new strategy games with Forrix to get them both used to them when they meet... every decade or so.
Falk - i think he's from a minor Olympian noble house? If so, then I imagine him being one of the few who could directly go into politics and not be Toramino (an aristocentric asshole :)). He even may incorporate some... less traditional ways of making himself known, including playing the harp while he spins charming talesa about his view being the best solution. Actually, he really likes playing the harp in general, though it looks pretty small on him.
Dantioch - I envision him being a scientist at a gene lab cause he already did wonders with the Sons of Dantioch which are something in between a baseline, an Astartes and a servitor. Like, he may even become one of the gene scientists under the tutilage of the Emperor himself should he be noticed (which... is unlikely thanks to Iron Warriors standing as the battery ram. Like someone from a different legion would need to somehow get to the Emperor how invaluable Dantiochs insight may be.
Soulaka - head of sector wide tournaments of different versions of the Dodekathedron's 'miniature simulations'. Does work together with the Imperial Army to see especially crafty strategists to fill their now reduced ranks.
Kroeger - ngl it's a 50/50 chance between him being in a gang after he essentially had no place to go and still only the desire to kill and be useful in the dirt. And he outlived his usefulness... and him maybe making the cut and starting some penal mining business where he works criminals to death and/or manages and secretly admires their fragile states hardening under the harsh conditions. He's brutal, but he'll prolly get digging with the boys too.
Toramino - He'll seize rule of the kingdom he's from through threats of squads staying loyal to him ramsacking his own birthplace. Basically an autocrat like Louis XIV. Begrudgingly submits to Forrix' logistical empire, Soulakas tournaments also favor Toramino's rule and had him as an honor guest twice. Still under Perturabos thumb, but he likes it there - the closer to being like the Primarch, the more efficient he'll become ine everything surely. His hobby is dancing with women. Just dancing. Hell he may even have his personal quarters staffed wholly by women cause they're more removed from the grime and dirt he's avoided experienced than men are. And they better know how to keep up with him on the dance floor!
