Making Ghost from Modern Warfare be In Rainbow Six Siege as an operator would be an awesome collaboration between games and I have all all the info for the operator known as "Ghost".
Abilities: he can pick up a dead enemy weapon or teammate weapon depending on the weapon his speed will change and can only pickup three weapons max to keep the character balanced.
He will also have a secondary ability that can only be used until he picks up a weapon off someone else. He will start off with an smg called "SPSMG9". Since you start off with an smg thats when your second ability is in use.
Ghost second ability will be stealth. He will be allowed to be dead silent for 5 seconds with a 10 second cool down. He will only be allowed to use this ability until he picks up a weapon.Lastly, his dead silence will be stopped as soon as Ghost fires his weapon.
Ghost being the only operator released would be a good idea due to the fact that he goes solo on many missions.
