Putting a Metro engine in a Locost should be pretty straightforward, following the usual dodges for converting FWD units to Hotchkiss Drive. You'll probably want a tall final drive, and a super-economy cam. The Locost instructions take care of basic structure and handling, so there's less need for those two books, except as the aerodynamics affect handling, and you can get as creative as you want minimizing wind resistance.

I think you could make a very light, rugged body by gluing up strips of Coroplast with Silicon Seal. A few temporary cardboard bulkheads establish the basic shape. After 3 layers, it starts to firm up very well, and there's no precision needed for an unwoven basket. You need the gaps to let the glue dry. You can build it up in thin layers to get close to the shape, spray it with foam, sand and add a thin skin of 'glass or even just Urethane to make it shiny.
