most divisions have the name and then the class above "super" but then instead of super lightweight we say light welterweight and instead of super welterweight we say light middle weight. also light heavyweight should not ba called as such, it should go as follows from middleweight up: middleweight supermiddleweight cruiserweight (old light heavy) super cruiserweight (old cruiser) heavyweight
Light Heavy weight has been around for so long they'll never change it. The fact is most of these super and light classes were added later, so they have less place in boxing then you trying to change the traditional weight divisions
Cruiser might be a naval reference. A cruiser is a medium size warship - slightly smaller than a full battleship - faster but with less armor. So, if a new weight-class around middleweight is needed we can call it "corvette" or "frigate"; I can't imagine lightweights will want to be known as "sloops" though!
