Welcome to the forum community!
As for your idea, first of all jet packs have been suggested before and won't be in. Secondly, FS isn't Battlefront, which just threw maps and kits and whatever together and made it a fun, but inaccurate experience. The FS devs strive to recreate the SW universe as accurately as possible, which means there won't be, for example, a map where you hop around on the Death Star in space suits.
