CS + X vs Aerospace Engineering acceptance rate

I have Computer Engineering down as my primary major, but I know UIUC is extremely competitive for all engineering majors. CS was my second choice but a) it’s not available to choose as a second major choice and b) I know CS in CoE is nearly impossible to get into. Having said that, I also know that getting into a CS + X in LAS is much easier than CS. But would CS + Chemistry, or CS and Statistics have a higher acceptance rate than something like Aerospace? I’m also super interested in Aerospace because aviation will be in demand in the near future and would probably want to minor in it if nothing else. Ultimately, however, I want to go to UIUC. So which major, CS + Chemistry, CS and Statistics, or Aerospace Engineering has the highest chance for one to get into at UIUC? Any advice would help, thanks!
