Oh, before I forget, I embarked on making some semi true scale marines to be honsou and his unit of chosen. The method is based on extending the legs and torso to make the proportions slightly more realistic; basically cutting the legs in a few places, adding plasticard and refitting and adding a lump of putty to the join between torso and legs.
By far the most unrewarding idea Ive ever had. It takes absolutely fucking AAAGES to cut all the bits, keep them together and refit everything with a 1.5mm bit of plasticard between them. I tried to do batches of 3, but ended up muddling leg bits and having to chuck away and start again.
Anyway, heres some irritating pictures to give the overall effect. I admit that it MIGHT be better when painted, but I'm not convinced of the balance of effort vs reward if I'm honest.
