Is this combination of Segmentata/Chainmail armour historical?

[[Legio_VIII]_Caesar_Libo]

Hello,

I was just wondering if this was historically accurate? I seen a few images of people wearing a combination of a segmentata top part with chainmail armour. 
Maybe this was a cheaper version but offered more protection? Maybe it was used in the Dacian wars? for better protection on the shoulders?
