I know, yet as Vartan says, if they are to be considered factional, as is currently the case, they should be there. It's no weirder than having Noricenes as factionals for the Gauls (or the Boiis as you have suggested yourself), and from reading the unit description they do seem to have more in common with the Casse than with Arverni/Aedui. As being consistent with how we determine factionals could in this case give use to a unit that currently sees none, I think it's fair to give it to them.
