Yeah Nixon's influence was not significant to Deng's reforms. Having Nixon as a POD isn't going to change anything.
But as an alternative to Deng's reforms, I seem to recall that there was another trend which advocated dominating and sponsoring the international drug trade (although that might have been a AH proposal and my memory is playing tricks on me).
The idea was in a similar fashion to how Deng intended for China to mess with global capitalism, instead causing as much destabilizing as possible by aiding the criminal underworld through training, weaponry and cheap access to product.
In practice, this would have meant that any militantly subversive group would have access to a sustainable income to support their movement.
