Need seasoned insight- Hopeful IB

Hi everyone- I'm a sophomore at a non-Ivy, well-regarded, small & econ-focused liberal arts school. I am looking to go into investment banking or equity analysis, but am struggling to find my focus/passion in college courses.

I currently have a 3.4 GPA as an economics major, and am looking to boost that. I do have some great experience in finance under my belt, which may help me in recruiting. However, is it worth switching to a history degree (which might get me better grades) if it means sacrificing an economics education at one of the best Econ schools in the country?

tl;dr is a mediocre GPA at a 10% acceptance-rate, Econ-focused school fine if I study Econ, or should I try to boost my GPA by switching to history?

Thanks for your help in this niche topic.
