I feel that they are a fine addition to the ranks of the IH.
That's comforting to know, thanks!
There's a number of ways the Iron Hands and their successors could react to this, and with the factitious nature of the Clans, we could see a similar situation to the Morae Schism.
And what do you think, would be the best reaction? What would you most like to see happening … ?
Ideally - the entire range I've suggested - this could be a really cool opportunity to re-introduce the antagonism between Clans that was mentioned in the Chapter's older lore - the return of a Primarch and introduction of enhanced marines seems like a significant enough event to produce a split in opinion within the Chapter.
It could also be used to reconcile the difference in background with regard to the Chapter we've seen over the past few years - the more Codex-compliant, emotionally-minded and less augmented Astartes we've seen with Kardan Stronos (i.e the Chapter as represented by more recent lore) siding with Guilliman and accepting the Primus Marines, whilst the colder, more individualistic compulsive-enhancers which adhere more to the older renditions of the background spurn Robute and his 'gifts'.
Maybe even have the Chapter completely fragmenting into two or more factions, with their Successors choosing sides or taking their own path.
Edit: now I've had this idea marinating in the ole' cranium for a while, here's how I could see the successors alignments:
Brazen Claws: Due to severe losses during their campaign of vengeance in the Eye, I could see them accepting the Primus Astartes as a way to save the Chapter.
Iron Lords: Apparently notably stern & xenophobic, this might indicate a mindset that wouldn't be especially well-disposed towards the Primus Astartes - then again, they could be seen as a saving grace in their increasingly desperate attempts to prevent Hive Fleet Kraken from assimilating the Barghesi.
Red Talons: owing to their involvement in the War of the False Primarch, I'd imagine they wouldn't greet Guilliman's return & his host particularly well.
Sons of Medusa: I'd imagine they could go either way in line with the Iron Hands, and with the similarities between the two Chapters, I could imagine the 3 War Clans separating in a similar manner.
Steel Confessors: Due to their origin, I'd imagine that the Confessor's first loyalty would be to Mars, so they'd be on-board with the Primus Astartes from the get-go.
There's barely anything on the Iron Lords, so I have no idea with regards to them.
One interesting facet of this whole discussion is whether any of the new Chapters created by Guilliman use geneseed from Legions other than the Ultramarines - if an entirely new Chapter of Primarus Astartes turns up possessing Iron Hands geneseed, I think things could get real interesting.
