I'd rather use "most famous" legions - thus V Alaudae & I Germanica YES, but VII Gemina - NO.
And maybe i'm not too precise when writing "most famous" - rather with most distinguishable names, so each legion (or most of them) have names specific to them.
BTW: do you have the file with "all" legions" or just with those "mapped"?
Anyway, maybe (for myself at least) I'll make the version with slightly different names...
@Mithick666:
Sorry, but this is impossible.
A unit can get the attribute "legionary_name" but it gets the name of a province it was formed (or a name assigned to that province), as described in descr_strat.txt.
Thus legion recruited in Antiocheia in Syria can ge given a name "Parthica" for example.
However, that way of naming legions is hardcoded and there's no way to assign any name connected to a leader or any other name...
