Pretty much, except you have to be somewhat conscious of the size of the kingsnake's head. Smaller kingsnakes just don't seem to be quite as stretchy (in the jaw) as cornsnakes. I haven't raised a lot of kings/milks, but I'll go with multiple smaller mice equalling the weight of a single Munson Plan mouse, for a king. Until it is an adult, anyway. For example, I might feed two fuzzies rather than one hopper for a while.
