I would put this in the category of possible but improbable. My basic skepticism is that I think it will be very difficult for any authoritarian government to generate the type of growth you are suggesting. I think if you have Kosygin push toward a mixed economy in the 60s and then have comprehensive political and economic reform in the 80s you could actually get some fairly significant growth in the 80s and 90s. This is broadly the South Korea ("ROK") model. In the 1960s-70s the ROK had a vicious, corrupt authoritarian government. They pursue managed capitalism in the 60s and 70s and begin political and economic reform in the 1980s. Their growth really takes off in the late 80s so that today the GDP of the RPK is about half that of the US (and three times that of the Russian Federation).
ROK in the 80s still had non tariff barriers but it was more liberalized than in the 60s and 70s. ROK in the 80s also gave out lots of loans peaking in 1988, gradually reduced export subsidies, and even thought they privatized banks, the Korean government still had a say in who got the top positions. ROK liberalized even more in the 90s, after 1992. PRC, today, is like ROK in the late 80s.
