If your student is super-interested in Brown, I would suggest applying anyhow and then taking to financial aid officer after admittance, especially if your kid has another admittance with better financial aid from another Ivy or MIT or Stanford (peer schools).
My son was a Brown student and we appealed our initial financial aid offer and they asked if we had offers from their peer schools so they could review and see if they had overlooked anything that the other schools took into consideration.
And we also had a one-on-one meeting with a financial aid officer who actually brainstormed with us on family financial issues that we might have overlooked and that would qualify us for additional aid.
and as I recall, you posted earlier about your irrevocable trust. This seems to me like something that a financial aid officer (anywhere, not just at brown) might take into consideration after admission as part of a professional judgment review.
Of course, you could also always make an appointment with a financial aid officer now and ask them about the trust and if they would consider a review based on the details . If you do this, make sure to make an appointment, not just ask the person who answers the phone who are often students who only know basic information, which this clearly is not.
