We do this. We're only a small 12-person software agency, we have two Elixir developers right now.
When we hired the 2nd, we looked for someone who had good knowledge of Node, Rails, Laravel or whatever and were excited to learn Elixir/Phoenix. Then they completed a Udemy course and started practicing. It worked out pretty great!
