You can create Private Galleries where you can host a feed of all of your extensions. When you update your extensions you can update the feed, and the updates will appear in Extension Manager as any other extension does from the main gallery. You can also create an extension that defines this gallery if you don't want your users adding the path manually.
(The direct answer to your question is it is also possible to embed VSIXes in VSIXes, but I don't think that's what you Really Want™ here since it has a bunch of caveats.)
