Considering an MSF to break into IB due to lackluster undergrad performance

I'm currently a rising senior at UVA - which I believe is a target school - working on a systems engineering degree and business minor. My GPA is mediocre (3.2) due to general slacking off in my sophomore and junior years in a tough major. This summer I was lucky enough to leverage my network to land a more technical internship at a MM firm, coding programs to run data analytics and gain insights for the firm's equities S&T division. Apart from that, I have no other financial experience besides limited personal trading (no university finance clubs or anything) and only one finance-related internship, the aforementioned one. To get a "reset" of sorts, I was considering pursuing a MSF at a top school to a) get an extra summer to pursue internships, b) get a new GPA to show along with my undergrad, and c) buy more time to learn the industry and network more. I would probably start preparing immediately after my internship concludes in two weeks, only going forward with the decision if I got a killer GMAT score to offset my GPA. All in all, I was wondering the viability of this option considering my situation and in general. I'm thirsty to learn more about IB (specifically IPOs and ECM) due to some influences from friends and my own ambitions. Thanks!
