Your OP is “Bringing Up a Son to be a Godol HaDor.” Thats of the elite few in every generation. You can be a Gadol Betorah without being a Gadol Hador. My Rav is a Gadol bTorah but I don’t think he is one of the Gedolei Hador, although he is an amazing Rav.
I have a better idea, why dont you become a Gadol Hador and stop trying to live through your child?!
