Depends what you mean by "easily."

Array "slices" in zsh only have start and end points, and are always in
ascending order by numeric position in the array.  So you can't do this
purely with parameter expansion in the general case.

This works:

for ((i=$#osvers; i>0; --i)) { osvers[i*2]=($osvers[1]); shift osvers }
