Maybe, but I'm skeptical that you could make a significant return on a collection of smaller (let's say $100M) companies. Statistically, most of them are going to fail, so the return on each of the successful ones needs to be pretty high in order to come out on top, but I just don't see how that could be the case unless their starting valuations are incredibly low. I can't see that being nearly as profitable as a single $50B unicorn.
