Alternate Idea for Multisite Setup

Hey guys,

Wanted to throw an idea out there about multisite setups. The current multisite setup in the guide is straight forward and a good solution. However, if you want to simplify it, you could separate the content folder or whatever other aspects of the site you want into Git submodules, which are then imported into your project (e.g., one content folder being imported into multiple sites). Thus allowing any part of your site to be reused. Would love to hear feedback, insight, or criticism about this method. Would it work, why or why not?
