 Hi

 I'm currently working on a plugin to build Microsites in a WordPress site.
 This allows to apply a different look and feel on a per page basis instead
 of having to create a new site in a Multisite setup or using CSS to
 overwrite values. For this the Customizer is utilized. In there for every
 Microsite the whole options for the normal theme setup is cloned. Menus,
 Widgets and all of the Settings.
 This works in 4.7 and with themes, that only use the Customizer, pretty
 well except for widgets. In the function dynamic_sidebar() in widgets.php
 there is no filter, that allows the change of a dynamic registered widget,
 as the index can not be changed before render.

 A demo of this plugin can be loaded at:
 http://plugins.th1nktank.net/microsites.zip

 Microsites can be added under Options -> General (you have to currently
 hit "Save Changes" after adding a Microsite)
 Then go into the customizer and change Menus, Widgets and Options for your
 Microsite (after applying this patch)
 After doing that, go into the options of a page a select a Microsite for
 that page.

 This is currently work in progress and a more polished version will
 follow.
