How to mount two HD to same mount point?

Is it even possible? I'd like to mount my two different hard drives to /home.

That won't work. You can create a subdirectory in /home and use that as a mount point for one of the hard drives. Or even create two subdirectories under /home and use both as mount points, one for each hard drive.

Is the reverse possible? For example mounting /home and /usr from one single partition?

You would still have just one mount point, either /usr or /home, but you could make /home a symbolic link to /usr, so that a path through one takes you to the other.

In fact if a user tells a Linux installer that there is only one partition to mount "/" every Linux installer will mount /boot, /home, /usr, /root..... as subdirectories of "/" in a single partition. I have installed over 100 of them and never met one objection.

If you want two hard disks for the same mounting point the right tool is called RAID.

Mount means to "connect" a device to the filesystem (at a mount point). As stated, you cannot mount 2 devices in the same place. (How would the file system know which one to talk to?)

You CAN mount a single device to as many places as you like. There is no ambiguity--you are simply accessing the device thru multiple pathways.
