Econ/Stat Fall 2017 Transfer. What classes should I take my first semester?

My priority is to get into the Econ major, while subsequently clearing out prereqs for Stats.
Fall is looking like this: Stat 134, Math 54, Econ 101B. Would this be too heavy for my first semester at Cal? and would it place to much risk in me getting into Econ due to the GPA requirement? Would putting off Math 54 and applying for stats in the spring be an option (like would I be able to finish the stat major in 2 semesters lol)
