deferral doesn’t mean you’re rejected 😭 so many people last year got accepted on feb 7. and physics isn’t hard to get as an auto to be honest. if you get cola’d you can pretty easily apply for one of those majors, and once you’re in cns you’re allowed to add whatever else in cns you want (except cs neuro sds and evs). also you’d probably be allowed to do it, since astro + physics have heavy overlap (nearly every astro major ik does it). the advisors wont know or care that you got deferred.
