Yeah, the Renegade ones are bizarrely stocky trolls. They manage to be bigger overall, but with stumpy legs, so they're like bizarre cranky beardless dwarf-soldaten. I was going to use them anyway by replacing the legs (the legs also have the wrong boots for early war/prewar anyway) and heads, but really there's got to be a better way.
For just about every other nation, either Copplestone or Renegade works fine for interwar troops, with only minor conversion or in some cases no conversion at all. It's only been German stuff that's been trouble. I've assembled a few characters from what you sent, from Artizan, 1:48 COMBAT, DUST Tactics, and will have a variety of sizes (I certainly don't insist that everyone be the exact same height), but I still need some average-sized (for my table), normal-looking infantry to tie the whole mess together.
