Is it plausible to depict the Segmentata using armor upgrades?

Or someone extending the game into AD which is where the LS was taken into use. By Legions who were, BTW ALWAYS armoured, no unarmoured Legioaires, ever. Auxilia often wore lighter armour, Legions heavier.

Cut and Paste from Wiki, whose Roman series of articles is not bad at all.
During the time of its use, it was modified several times, the currently recognised types being the Kalkriese, Corbridge and Newstead types. There was, however, a considerable overlap between these types in use and the Corbridge and Newstead types are often found at the same site (e.g. at Caerleon [Wales], Carnuntum [Austria], Carlisle [England] and Leon [Spain]). It is possible that there was a fourth type, a hybrid of the banded armour together with scale shoulder defences. However, this is only known from a badly damaged statue originating at Alba Julia in Romania. The currently accepted range for the use of the armour is from about 9 B.C. (Dangstetten) to the late 3rd century A.D. (Leon). However, similar armouring techniques were used during the 16th century, employing sliding rivets and this was known as anima. Introduced in the early 1st century AD, the armor saw widespread use during the period of 2nd-3rd centuries AD.
