I suppose everything old becomes new if you wait long enough. Two-stage (or more) power supply filtering was the norm for some 50 years in vacuum-tube radios. But scaling for frequency and current does require a bit of work. The quality of circuit simulator results ALWAYS depends on the quality of the component models. It takes great wisdom to know when you can ignore any of a component's parasitics. The old axiom is, of course, "garbage in, garbage out."
Don't forget: Spice lies! (Courtesy of Bob Pease ;-)
So, there is no clue here about inductor parasitics and other component side effects. Does not care, as long as you know what you're doing. Wuerth shortly will publish a book how to use LTspice with proper inductor and transformer models. Very promising! I love those new goodies to play with, I heard march next year.
