I wonder what influence Grayson will have on some of those planets? Thanks to Honour the Hades surviours had the chance to settle in her Steading or join the Protector's own and a lot of the recently conquested planets would have had significant public and military figures on Hades.
Sure lines of commerce will have a big influence on the viability of some planets independance - so I could see some near Trevour's Star leaning towards Manticore as the liberating force. Others towards Erewon on the southern border.
Of course those of to the North and East are currently out in the cold without trade through Haven but also a long way from the action. So Going independant and refusing to support the GA may well be a viable option out there.
Coming back to Grayson - what will their peacetime role be? I suspect there is an area between Manticore and Haven that their Navy will now be responsible for patrolling and diplomatically picking up trade relationships with some of those newly independant planets would be an economic advantage. Those Hades survivors will of course be a big help with establishing those connections.
