A unit citation ribbon? Is that the same as the Air Force Outstanding Unit
Award, awarded to units "which have distinguished themselves by
exceptionally meritorious service or outstanding achievement that clearly
sets the unit above and apart from similar units, the services include;
performance of exceptionally meritorious service, accomplishment of a
specific outstanding achievement of national or international significance,
combat operations against an armed enemy of the United States, or military
operations involving conflict with or exposure to hostile actions by an
opposing foreign force."

Regardless, after a lengthy search, I could not find anything that would
agree or disagree with the idea of personnel later joining a unit wearing
the awards previously presented to that unit. Therefore, the only thing
remaining is the general regulations against wearing unauthorized ribbons
and awards. And, lacking anything else, I guess I'll leave it at that.
