The idea of having an authority site that can help you to launch new sites is not a crazy idea, at least from my observations.
I see sites ranking in the top 10 for single keywords I want that have links from only one site ... an authority site which I'm sure is owned by the same person (or they are just subdomains or subdirectories of an existing domain).
Starting from scratch with every new domain is no fun.
Not saying your particular scheme will work just pontificating...
