I was browsing through a listing of US military aircraft and came across a couple interesting but unbuilt designs, the Douglas C-114 and C-115. The C-114 was a C-54 powered by four Allision V1710 engines while the C-115 was a C-54 powered by four Packard V1650 engines. I could see the North Star conversion being used to model a C-115 and perhaps something like four P-40E, or later model P-40, engines, cowlings, and props used for a C-114 (alternatively, blend in with F-82 upper cowlings and props to use later model V1710s).
