This is highly dependent on the discipline and particular field.
For topics with a large number of practicing labs that make use of relatively accessible tooling you might be able to pull off such an approach.
Other fields require customized, incredibly expensive instrumentation. Physics and certain areas of biomedical research are examples of this. It's not uncommon that fewer than ten labs in the entire world will have the capability to perform a particular highly specialized technique.
Even in the largest fields though, it will be your peers reviewing your grant applications at the end of the day.
