I had a few ideas on this too, since HBG and CCM 3D print various pieces:
light cruisers 2/3/2/10
heavy cruisers 4/3/2/14
light aircraft carriers: 1/2/2/12 one AC
tank destroyers: 3/2/2/5
med tank: 2/2/2/4
heavy tank: 4/3/2/8
self propelled artillery: 3/2/2/5 can blitz
medium bombers 3/1/4/10 can strat bomb
Feel free to add ideas, or comment / modify mine
