This would be an administrative nightmare. But for switches, it would at least technically work. You would lose the end-to-end troubleshooting, and I wouldn't see real benefits. Which advanced feature are you most interested in? When you say "Core with advanced features", I could only think of Netflow. For that, a 9300 in only Meraki monitoring mode could be a solution. I didn't test it that way but I assume that you could configure NetFlow the manual way, export it to an external collector, and keep Enterprise licensing.
