As long as it isn't wildly, garishly anachronistic? Very. In these planning stages the parallels to the Gauls are obvious enough, but there are Pictish, Frisian, even Etruscan elements as well. So you're not signing up for a purist experience by any stretch.

You'll soon see too that even the geography will encourage a wide array of cultures among the tribes: one or another people runs over mountains, coasts, plains, and forests; they are behind the natural barriers and in the fore; some relatively safe, some still fighting, and some already broken and bonded. So get creative!
