Can a V-8 diesel engine be swapped into a 2004 ford ranger?

All right i am working on an off road build with my 2004 4.0 L V6 Ford Ranger. I have already installed the Super lift complete lift kit with after market drive shafts, skid plates, role cage, micky thompson baja tires/ bead locked rims, warn winch and off road bumpers, under carriage skid plates, l.e.d lights. I want to know if it is possible to replace the stock engine with a V-8 diesel engine.
