Shortly after the fourth edition codex came out I revamped my lowly Ulthwe wraithguard unit to bring them back to prominence with their then new rules. Part of this included putting them on larger, terminator-sized, bases. I was particularly happy because, at the time, it made them much more stable.
5th edition came and went, but in 6th new wraithguard models finally came out and the bases fit. At that time I was fitting out new plastics for close combat and swapping half my classic squad for d-scythes. I then received another box of 5 as a gift and figured I'd fill the basic cannon unit back to full. This revealed a problem, the old unit looked weird mixed into the new unit.
The height was similar, and swapping out gun barrels was an obvious step, but they just looked out of place, and the problem was the shoulders. The classic wraithguard don't have pauldrons and it means they lose that exaggerated triangle torso shape that Jes replicates throughout the army. To rectify this I've added the hip plates from the plastic models as pauldrons to the metal, and overall I'm very happy with how it blends the old unit with the new one.
