What "migrated faction" options are there?

[QuintusSertorius]

lusotanii on ireland should defenitley work, factions like epeiros and kh have numberous options, but im afraid that carthage has little to no alternatives, maybe u could put them close to the Saba? They got the same culture after all.

I think I might use FD to give the Lusotanii southern Ireland, especially now the Casse have conquered all the British Isles and have nothing to do except occasionally fight the Aedui when I transport a stack of theirs across the Channel. Tempted to use the Casse as the Belgae, since those two provinces are homeland for them. They might actually be able to drive off the damned Sweboz as well, since the Aedui don't seem up to the task of holding Bagacos.

I've already put Epeiros in Kyrene, in preparation for destroying them not too long off (it's 180BC in my game, just 13 years to go).
