In an analogous situation. I try to think of my current work as a stepping stone to other opportunities, but admittedly it's tough. I'm also genuinely interested in data science, but am skeptical that to do data science you have to 'retool'. I think it's about striking a balance between the skills you have and developing in areas that make you more productive. Good employers know how to motivate people and keep them engaged (if they speak up).
