Perhaps they can keep the awards and ribbons, but limit the display to twelve, or three rows. Valor ribbons at the top.
They could always grab up some Boy Scout sashes.
During the Vietnam period it was standard for a maximum of three rows, combat awards on top. Unfortunately this was not a military regulation, and senior officers decided that it looked better to put all their awards on. Vainglorious comes to mind, especially when they look like a sausage in uniform.
