Possible to update a Sierra sandbox to High Sierra?

Potentially stupid question incoming:

I'm running an iMac with the latest version of Sierra. I want to create a dupe of my current system and upgrade that to High Sierra in order test Adobe CS5 compatibility.

My initial thought was to create a Sandbox-Shared users volume and upgrade that to High Sierra. The logic is that Sandbox-Shared users moves 3rd party apps over to the sandbox, hopefully giving me a more "real world" experience.

The idea is that I want to see what happens if I update the OS in place without having to reinstall any Adobe stuff.*

The more I think this out, though, I'm wondering if should just grab one of the external HDs I have and install High Sierra directly on it. I can create an installer using this method:

Is it possible to update a Sierra sandbox to High Sierra, or am I completely misunderstanding how Sandboxing works. TIA for any help.

*I know about the upcoming 32-bit app apocalypse and am aware of how old CS5 is. Just trying to keep costs down.
