I agree, John's method is more elegant. Just take care about the order of dimensions in the hyperstack, it must be first frames and then slices.
This macro does the job, I guess:

// -------------------------------------------------------
// separate odd and even slices in a stack

getDimensions(w, h, c, z, t);
run("Stack to Hyperstack...", "order=xyctz channels=1 slices=" + (z/2) + " frames=2 display=Color");
ID = getImageID();

run("Duplicate...", "title=odd duplicate frames=1");

selectImage(ID);
run("Duplicate...", "title=even duplicate frames=2");

// -------------------------------------------------------

Regards,

Daniel
