For example : if there was contract from Yuri G, then he must also included in flight, and I would be very grateful if the pictures of them was based on their real human form, and if they're deceased (hopefully not), they just disappear from contracts selection and maybe we get some penalties.
If this really happen, I prefer this Yuri G pic :
Devs can remake this with their own style, and By The Way this one is my favorite
