Upfront can I download "bare" theme

Can I use Upfront as a bare theme? I tried to introduce the "Fixer" theme in my site that is under construction, but it changed far too many elements that I already had in place. I am especially interested in using the builder part of the theme, and wish to use as many elements and plugins from WPMUDEV as I can. Can I activate the theme like that or am I bound to start all over?
