It's completely unrealistic.
Firstly, for many children, it would be an achievement to read 100 books of any kind by the time they leave school, never mind 100 classics.
Secondly, I have read some of those books. I remember reading The Secret Agent at school and it was pretty much an exercise in exquisite torture. A lot of those books are quite hard to read thanks to the archaic language and some of them wallow in depression. To make the average child read these books is to teach them that reading is a really nasty boring chore.
Thirdly, the idea that you should read Romeo and Juliet instead of watching it as a play is totally absurd unless you are studying it in Eng. Lit.
