Moving from Testing to BA


I have over 4+ years of experience in testing and I have mainly worked on client requests. Now that the expectations of employers about the output from testers has risen, and also because I am keen, I was thinking about working in a mix role of Tester and Business Analyst. I did work as a BA on freelance basis to see how it works and I could relate fairly well with it. Understanding users requirement, mapping them, feasibility studies, product improvement really interests me. I also know documentation side, agile methodologies but I need fellow testers views on:

  1. Whether such a role exists or does it make sense for someone to row into two boats together?
  2. Whether employers are open to appointing BAs with a testing background?
  3. What are the must have skill sets to be in such a role, if it is advisable?
