I'm not 100% getting what ur saying, but essentially with every OE unit they are versions of the unit if they were to attain power that they never could in reality. e.g. Azurai's OE is him if he were to gain the power of the Ancients that he so desired (hence both horns and wings).

So having units that aren't OE units, but could still reach lvl 150 would be impractical since they could never reach that power in reality. As for Karl, Seria, Lugina, Paris e.t.c. the ones we receive are all mock units made by Noel who also made OE units so it would make perfect sense for them to be branded as Omni's since they weren't even real in the first place.
