You will hit two problems in this "only hire virtual juniors" thing:

* the wall of how much you can review in one day without your quality slipping now that there's far less variation in your day

* the long-term planning difficulties around future changes when you are now the only human responsible for 5-20x more code surface area

* the operational burden of keeping all that running

The tools might get good enough that you only need 5 engineers to do what used to be 10-20. But the product folks aren't gonna stop wanting you to keep churning out the changes, and the last 2 years of evolution of these models doesn't seem like it's on a trajectory to cut that down to 1 (or 0) without unforeseen breakthroughs.
