Well sure. He would have to hire a team of people and they would have to learn to work together. Not only that, but he may have to hire a project lead, to keep the stress off himself a bit; but that is if the kickstarter project promised a bunch of stuff to be along the lines of Divinity or Pillars. He could start off with a narrow scope. Hire 2 full time people and use a brand new engine if stretch goals are met. And then he could keep the gameplay and writing the same, without re-inventing the wheel. then if that project is a success he could do another kickstarter, trying more new things. It would take a rush of new-found ambition he may not currently have. But he could do it.
