Fwiw, my wife worked in a SD in NJ where there was a high concentration of secular Ashkenazim (it was right next to a major NJ college town). Several kids (typically kids of tenured professors) there were partially homeschooled but came to the high school for sciences - mainly for the lab work. Different state and over a decade ago, I realise, but that always struck me as an almost perfect blend.
