Two-level multisites in WordPress

Sub-directory blog on a sub-domain WordPress network site
You could create a network-of-networks, using the WP Multi Network Plugin. The primary network would be a subdomain network, and the subsidiary networks would be subdirectory networks.

Why can’t a WordPress network (multisite) in it’s own folder use subdomains?
I figured it out. The fact is, a network can use subdomains or subfolders, even when WordPress is installed in it’s own folder as long as the main site’s HOME URL is set to domain.com and not to the sub folder location.

Don’t allow access to wp-admin but allow admin-ajax requests to be fulfilled on frontend?
You don’t need to check is_admin because the function is hooked to admin_init, so is_admin() is always true in the callback; that makes that ( is_admin() || !empty(DOING_AJAX) ) always verify as true.

Can’t add user to blog on registration (Multisite)
Regarding the update part in your question: I think the problem here is that you’re missing the number of accepted arguments in your add_action() setup.
