Most major pops already stand out by having somewhat higher wrench or coin production then other harmonised pops
Gremak also keep their "Slavemaster" trait which is really cool if someone thinks to combine their harmonised version with slaves (this is difficult to rationalise as harmonised pops are better then slaves unless food is needed so maybe in case ther are a considerable amoun of non-harmonizable minor races in the empire)
Orthin, on the other hand, have the same base value as Humans though being the best in research. They could still have lower research but higher then other harmonised pops to make them unique when having been harmonised
Humans are generic yes but I guess that is the idea here: their bonus to reproduction rate would not translate well to when they are harmonized due to the way it was implemented. If they would nee to stand out somehow maybe via a new trait like in case of Gremak
Lummox and Algorians also have base value but they are minor races so it does not matter much - how abouth these could be "transformed" to their own type of cybernetic ground shocktroops though via the same mechanic the Gardeners will use
