Yes, the Aero Commander/IAI Westwind replaced this biz-jet project.
After North American Rockwell bought out Aero Commander, they found themselves manufacturing two competing biz-jets: Aero Commander (mid-wing) and Sabre-liner(low-wing). To avoid anti-trust laws, NAR sold the Westwind to IAI. IAI built a few hundred Westwinds before converting production to the Astra, which looks like a Westwind updated with a swept, low-wing, etc.
You can see designer Ted Smith's influence continue through the entire A-20, A-26, Aero Commander twins, Piper Aerostar, Westwind and Astra line.
