Originating from any of those nations is fine. Glamours for them even exist ingame already. Play the character you like, enjoy yourself, and don't fuss overmuch about what others might think. Use the glamour sets, read up on places like Radz-at-Han and their alchemical bent, to get an idea of what someone from there might be like.
Even the Echo is getting played up more in recent MSQ with Arenvald, Fordola, and Garlean science. We now know that it's not just the WoL who can fend off and survive primal attacks and tempering. The degree of Echo capability you want for your toon and how they got it is entirely up to you.
