I see with new blog templates it is not possible to copy

Hi,

I see with new blog templates it is not possible to copy the main website so i have made a new site similar to the main domain in a subdirectory. What i want to know can i make a complete copy on this site from the main website and use this copy as a template for my users so they have a fully optimized monitized website that they can use as a blueprint to promote their own business? So yes can you give me examples or more information on how a can do that? And if they use that template will it also copy the plugins or only the theme?

Thanks.

Kevin.
