Rebranding according to what's in demand is all fine, but if you choose data science please make sure that you actually have a solid understanding of statistics and software development. Because ultimately that's what data science is.

"Hugely credible" and actual experience in data analysis/statistics are completely different things. And if you don't have the statistics/math background, you'll find out that now instead of just programming, you need to learn programming and statistics. Which might be too much for someone who doesn't know where to start.
