The answer is No and Yes.
When you run the X-Plane installer, it will only install components of XP into its working directories. There is no option to download one giant compressed image.
However, after installing XP into the “download machine”, you can copy it over. Simply copy the entire working XP directory structure onto a USB drive then paste it onto your target “sim computer“.
BTW, expect just over 60GB, including the full global scenery.
