The problem with this idea (and don't get me wrong, I love the idea!) is that as automation takes away the busywork, what's left requires an increasing amount of specialized domain-specific knowledge, and this kind of knowledge is expensive. Finding someone good with the right broad skillset is hard enough. Then they also need just the right combination of experience, or extensive on the job training, to be useful in the role. And once you have the right person with the right knowledge, they then need a lot of knowledge about the specific project they're working on, which also costs time and money for them to acquire. Also as your hours worked per worker goes down, the number of workers goes up, and your communication and coordination costs for a project are at least quadratic in the number of workers on that project. As a consequence, it costs more than twice as much to run a project with two half-time workers as it does to run the same project with one full-time worker.
