You have a solid profile -- although keep in mind that there's also a lot of IB/PE dudes like yourself applying with similar resumes. So it'll come down to how well you execute the applications, and luck (of course). Your chances are reasonable enough that it's worth at least shooting for the top 7 -- whether you want to go beyond that is really a matter of personal taste (whether you feel it's a "top-7 school or bust"). If you're looking to stay in something finance-related short-term, then it's probably wise to just focus on the top schools. If you're simply looking to get the hell out of finance (i.e. you're interested marketing, nonprofit, etc.) then you can probably look outside the top 7 as well.
You can keep your top 4, add whichever school from the other list, and you should have some shot of getting into at least one of them -- but again, it's hard to say how much more competitive it will be for finance dudes this upcoming year. This year has been pretty brutal - there's simply a lot more folks with IB/PE experience up to last year simply because the industry itself has seen a huge expansion from the 2000s onwards (which saw more funds, more headcount, etc.). Couple that with the fact that adcoms know that as a group, the IB/PE folks tend to focus on finance jobs post-MBA (no matter what the individual narratives are for each applicant, as a group the majority ends up in finance post-MBA - they just won't know which individuals) - and it's more of an uphill climb compared to a few years ago. In fact, while it's always been the case that folks from top tier consulting firms tend to have more success at getting into top b-schools compared to the finance crowd, it's probably even more so the case now.
