There was a fair amount of variation even within the legions for example Garviel Loken looked nothing like Horus & neither did a fair number of the rest of the legion. The same was true of most of the other legions, while a large number echoed their primarch there was always a fair few who didn't. The one exception being the Alpha legion who used gene therapy & surgery to all look like Alpharius. The lesson here is that as their were always astartes who didn't look like there gene sire there would have been little question to having a fair number of non standard legionaries in any legion.
