Can an a african grey parrot be kept with a Blue and Gold Macaw?

I have an Africian grey parrot that is my sweet baby. But I am considering taking in an Blue and Gold. I want to know if keeping them together eventually will work? Because I need them to be able to be together in order to spend enough time with them each day. The majority of the day they will be either on me or in the same room on a swing or stand. So they would need to get along. Please only experienced bird owners respond.
