My guess is the only additions, if there are any, will be Ant Man & Wasp. Either one of them or both of them.
You don't think Falcon will join? As much as I wanted Ant-Man and Wasp in the sequel, there is a good possibility that they wont show up till the third. (Although I love everyone's theories about them showin up in 2!) That being said however, I think just from an informational standpoint, if there are any new additions it'll be Falcon before anyone else.
