I followed your instructions and now have Sierra on a partition of my hard drive. Your instructions looked like something even I could follow and it sounded like a good idea, try before you commit. Once installed, restart with the option/alt key held down, select the new partition and reboot. You might want to make a copy of the installer outside the Applications folder to avoid having to re-download it in the future. Download the installer from the App Store and when it starts, point it at the new partition. Name it something and select Mac OS Extended (Journaled) as the format (step 5).

Select the newly created space and hit the + button (step 4). Using the /// at the bottom move it up (step 3) until the size box decrease by about 50 GB. Open Disk Utility, select your hard drive (step 1), then the Partition tab (step 2), and select the partition.
