DD sounds like a match for mid to top tier LAC. Would she be interested in a women’s college? Bryn Mawr, Smith, Mount Holyoke Scripps? I think they are all T50 and with “reasonable” acceptance rates and rigorous academics. Also they might appreciate eclectic interest and hobbies in lieu of traditional ECs.
Some others LACs that aren’t impossible: Oberlin, Occidental, Vassar, Macalester.
Look for need-blind schools for both kids. I have twins myself (HS Juniors). Totally different people, different interests, high academic achievers but in different ways. Oddly they are looking at many of the same schools which could be a disaster if one twin gets in everywhere and other doesn’t!
