Spitballing here: So what do you do with all the surrendered Green Household guards in King's Landing?

So we see the vast majority of the Green Targaryen household guard in the Red Keep put down their swords. They're probably, mostly, the Targaryen Household guard stationed there for Viserys, when the greens took over they were forced to change wardrobes to support the new Targaryen King.

Most of them are likely not Hightower men from Oldtown, but Targaryen Household guards from the Crownlands that serve house Targaryen directly by being stationed to the Red Keep.

You have 2,000 Gold Cloaks that are helping you secure the Red Keep for now, what do you do with the surrendered Green Targaryen household guards?
