Switching from M&A to Corporate Finance

How possible is it to switch from M&A to Corporate Finance (i.e. FP&A, etc.) without needing to downgrade position?

I will be starting M&A in a Big 4 (PWC/KPMG/D/EY) soon. I am considering making the switch (probably after 2-4 years) due to the following reasons:
1) The deal flow of the M&A market in my location isn't good. Additionally, there aren't many PE/IB/HF/CD jobs around.
2) In contrary, there are plenty of CF jobs around. Also, I'm fine with CF; I don't hate it or anything. Job stability and growth are important to me.
3) I enjoy being in a large institution for social reasons. Lots of the available PE/IB/HF/CD jobs in my country are for small companies.

Being a finance manager/director/CFO in a large corporation over the long term is appealing to me. So my ideal career path would be: M&A > Finance Manager (CF) > Finance Director > CFO

Nevertheless, I still do hope to start off in M&A for the exposure. From the job listings that I see in my country, many of the available Finance Manager/Director positions require prior experience in FP&A, Accounting, etc. Would it thus be possible to jump from M&A to CF roles, since I will not have much exposure to Accounting?

Thank you. I'll appreciate all serious replies.
