Is it possible to replicate the exact behavior of the FAB from "Inbox by Gmail" app?

Is it currently possible to replicate the behavior of the "Inbox by Gmail" FAB with this library?

I am talking about this:

In particular I am interested in:

1. (collapsed) Having an icon A and no label on the FAB
2. (clicked collapsed) Animate the expansion and the icon swap form A to B
3. (expanded) The background is faded
4. (expanded) The labels have a white background and grey text
5. (expanded) The big FAB button, red in the screenshot, has its own label
6. (clicked expanded) It starts a custom action and is toggling the FAB collapse
