HaL, your idea sounds good on paper, but you don’t seem to realize how impossibly difficult it would be.
You’ll never make the parents happy. If you invite everyone to benefit from your ‘system’, they’ll complain about their children being exposed to a child from a home where they don’t eat galla on Shabbos, or the mother wears nail polish, or the father was once seen wearing a shirt with a stripe that was not pure white. If you are more selective then there will be an outcry over that.
Everyone will disagree about what you are teaching those little kids- too much, too little, and everything in between. Don’t even get me started on translating a passuk of Chumash into Yiddish. And learning Gemara too fast, or too slow, too much bekius, too much b’iyun, or just not perfectly enough for their little geniuses.
And who, may I ask, is going to pay for this venture? Ha! Didn’t even occur to you, did it?! Every single parent will tell you they can’t afford to pay for your service. And just wait until a parent sees one of your teachers or administrators buying more than a milk and a bread at their local grocery, or actually driving a car, or wearing shoes that are still attached to their soles… Do you realize the implications? the horror? that you would have the chutzpah to ask them to fund this?
No. I vote your idea has too many pitfalls to be viable.
Let’s go back to yungerman’s idea.
