Hey again, does my answer from reddit not solve your first 
problem (keeping the existing file structure)? As mentioned, 
using Unity for the tests does not really make sense with D, 
though it might be possible to use it with dpp ([1]).

Regarding your second problem: The Arduino UNO is based on the 
ATmega328P, which is an AVR chip. There is currently no D 
compiler available, that targets AVR, so you won‘t be able to use 
D for programming your Arduino UNO for now. There have been 
discussions about this ([2], [3]), but for now it is simply not 
possible.
