If the developer beta 8 installer is any indication while you may be able to RUN High Sierra on an internal SSD formatted HFS+ you will not be able to INSTALL High Sierra directly onto an internal HFS+ formatted SSD. (No HFS+ option was offered by that installer on my new MacBook Pro.) However, you should be able to install it on an external HD and clone that to the internal SSD formatted HFS+.

We've reached the exact same conclusions about installing and running High Sierra.
