The German army attempts this with "JFST" (joint fire support teams).
I suspect it would be a "no enough for everyone" solution in a hot conflict, to be confined to the Schwerpunkt of the Bde (plus probably one or to on dominating heights).
edit: To clarify: I don't whether it's actually a matter of careers. We did combine mortar, arty FO and air attack forward controller, though.
