I've decided to make several variants of the same sides for "USM" (cis.lvl, rep.lvl, imp.lvl, and all.lvl)
Say for example I've created the original side all consisting of Battle Droids, I later release a variant that is entirely compatible with the old one. This new variant uses Magna Guards, easy right? Well the only dilemma I've come across is the localization.

If I were to replace the standard Battle Droids with Super Battle Droids two things would change, the weapon models (Blasters to Wrists) and the Super Battle Droids will replace the standard Battle Droids. The name's would remain the same, really wouldn't fit right.

What can I do to make the localization swap easy for the player?

Spoiler:

You could make more than one common.lvl (I think that's where the localize stuff is munged) than they
just need to replace it once they change the side...

A suggestion for the CIS sides: Neimoidians, Mandalorians?

If I could put together an installer (Similar to how the Unofficial v1.3 Patch did it) it would be simpler. (For the player not me) First select the faction you wish to change. Then select the appearance of the faction. This replaces the ***.lvl file with the selected appearance and replaces the common.lvl with the corresponding side variant.

Really loving the idea of having a Magnaguard as a sniper.
