If the idea is only to maximize chances of getting into a “prestigious” university, then maybe but I would strongly caution against this. OP should follow their true interest.
Would OP be happy enrolling (if admitted) at one of these over any other choices? Seems like not, as OP seems to strongly prefer Stanford.
Again, unless this is a pure prestige hunt I wouldn’t consider Chicago a top CS or Chem school.
OP’s chances at these schools will be quite a bit lower in RD vs ED/REA.
I think OP will do better picking their top choice and applying REA or ED there while also applying EA to other top public schools.
