Can I change my Schengen Itinerary after refusal for the re-application?

Yes. But keep in mind that a steady, well-documented income is more important than the assets you own.
You can reapply immediately, at the same or a different embassy. Where you make your application depends on your itinerary. The Greek officials will see your visa history, of course.
It might make sense to write a short paragraph in a cover letter to explain that you have been refused before because you did not submit enough documents, and that your itinerary changed accordingly.
Getting a visa for 14 days will not be easier than getting a visa for 24 days.
