huh? What do you mean by I was planning? Since you've got all the tools and skills, I say, go get your CPA license and you're all set for the remainder of your life. If working lengthy hrs for the first 3 years or so sounds daunting, then you might wish to pursue some different career. Else, you're pretty much well set from what I can tell. 

Getting a CPA license and then pursuing SAP Fico would be a waste of your CPA license, imo.
