I don't think that can be made to work with dependencies. To work kernel-core 
would need to depend on kernel, so that installing kernel-core would require 
kernel which requires kernel-modules, which is a problem.

In most cases old kernels get removed by updates, so most people aren't 
going to try to be removing specific old kernels by hand. For those that 
do, using kernel-core instead of kernel isn't a big deal. The main thing 
is that the change should be documented in the release notes (and perhaps 
other places) to avoid confusion.
