Hello,
You can install the Sparky Page Builder with any template. However, on some older templates (such as Luxury), all the content will need to be re-created in the Sparky Page Builder because the older templates use the default Joomla editor.
The list of the templates for which content is created with Sparky Page Builder is here

(see the bottom of the page).
Regards,
Milos
