Motive power plans

so i plan on making my own locomotives from stock motorblocks or broken locomotives, one of my ideas is to make a 2-8-0 from a piko 0-6-0 motorblock and here is a drawing

pretty nice eh? well its heavily inspired by a South African Railway 8Y class, a Victorian Railways K class, and various Canadian Pacific Locomotives i plan on making the boiler and smokebox from PVC pipe the cab and tender will be made from polystyrene sheets the cylinders, smokestack, steam dome, firebox, splashers, headlight casing, and misc parts will be 3D printed likely from Acrylonitrile Butadiene Styrene (ABS) filament with either Kadee, Aristocraft, or 3D printed couplers.

Other plans for locomotives include a Beyer-Garrat made with Bachmann Parts, a Great Northern Prairie from a New bright 2-6-2, and maybe a Mallet or Kitson-Meyer using the same methods
