Well they still have to install CPython to install Jupyter and even Python3 if they want multi-user... so I’m not sure that would “screw” them. (or I don’t get why you mean by screw them).
Release schedules and development would be swallowed into Python. If they need a bugfix for Julia or R, they have to wait for the next release of Python. There would also be Julia and R related issues in the CPython bugtracker.
One possible, simpler thing would be to ship a minimal python kernel  that ‘only’ requires PyZMQ.
This would require a C++ compiler. Currently we can build CPython with just a C compiler. A language change is not a minor detail.
