This could work.
To make an analogy, PhD students usually don't have a project to work on when they start and if they do, that usually changes. Yet many of them become excellent researchers and leaders of their field in the future.

That's probably stating the obvious (but sometimes it's worth doing that).
Edit: The analogy does works but you might want to consider subjects as 'startup areas' e.g. consumer, enterprise, infrastructure, etc
