Are the Skins of Coustilliers and Robert Guiscard similar?

Based on the LotW event, in which Knights get the skin of Roger Bosso, I am making a visual mod for the Knight line to use lances.

I got Edward Longshanks for Paladin skin. His large shield is quite great since Paladin have +1p armor over their predecessors. I got Frankish Paladin and Bernard for Cavaliers but their graphics become invisible at certain angles (idle/walking). I was thinking about Robert Guiscard to be made Knight, but now I think he looks similar to Coustilliers.
