You can't "share" mount points between devices.  You could setup RAID or LVM
to combine the devices into one device, but it is far easier to simply move
your home directory to the larger drive and mount it on /home.  After you
are sure the data is copied to the new drive, be sure to delete it off the
old drive to recover the space on your root partition.
