You are being stupid.
Is your daughter’s only criterion that the boy be a full time learner, or is she interested in other things too? What kind of hashkafas hachayim does she want the guy to have? What does she want in regards to chitzoniyus? You can’t just look at one thing and say, oh, Brisk is what is good for her. Maybe she needs a shtarke Mir guy. Or something else. Just don’t focus on only one thing.
