they probably will seeing as the cover for this year was the 5 squads' leaders (doc, hibana, thermite, cav and kali) on one side with deimos on the background
On what charge? Three of the former Rainbow operators, Finka, Smoke and Ela, were military, so desertion could be a thing. The other two, Pulse and IQ were civilian law enforcement. There are no similar charges, that I can think of, that can be brought against them. Additionally, I doubt that Kali would have left her company open to any charges stemming from these operators leaving Rainbow, and their parent organizations, the FBI, the British, Polish and Russian Ministries of Defense and German GSG 9. Also, if R6, Splinter Cell and Ghost Recon (Wildlands and Breakpoint), are all in the same continuity, Finka is deployed to Auroa for Op Clear Sky, along with Ash and Thacher, with Lesion as operational support. So, in that case, what you want does not happen.
