launch new space station modules the same diameter and length as spacex starship on top of spacex heavy booster

when new space station is built, it would be more efficient to transport space station modules on top of spacex heavy booster instead of inside a craft like a spacex starship or space shuttle 

those space station modules should be the same diameter and length as a starship 

so that every space station module is far larger than international space station modules 

this would give humans aboard new space station much more volume to live more comfortably in
