is IB a pipe dream for me?

Finance major at a west coast non target. Big state school, T50 overall but complete non target

Have about a third of my degree completed, finance major with a ~ 3.7. Expect it to go up soon, recent grades have been much better than before (20, supposed to be a junior after the summer but was a fuckup and withdrew from all my classes one semester, and didn't do well my freshman year. Fixed that recently) 
Have had one mediocre tech internship, hardly counts tbh

I wasn't really sure what I was doing before, but recently I became more focused on my career and trying to do well in life

Recently I've been interested in IB. I was looking at some semi targets, and transferring into them, I'm somewhat confident that if my grades do improve, and I apply next year, I'll be able to get in (comparing average transfer GPAs and some online anecdotes, I also had a near perfect SAT if that even matters at this point). Something to note is that a lot of these schools are sought after for their business school, while I'd be transferring as an econ major to the liberal arts/equivalent college in most cases, as they're a lot easier to get into

At that point I should have completed around half my degree and be a junior. Will that be enough time to network, try to land internships, etc and get a good IB placement? Am I wasting my time?

I appreciate honesty. If this is genuinely extremely difficult, I will take a different path and look for something else. I understand the market is bad and every job is increasingly competitive every year.

Thanks for any advice
