Can a stream be shared across RTC Projects explicitily

Problem:  We have  2 projects that are being used for development purposes.  We have 2 projects because we don't want the users of Project A to have access to the code in Project B.  There is a stream that resides in Project B that Project A needs access to you, but we cannot allow access to these users to Project B. 

Can this stream be moved to Project A to allow visibility to users in Project A and B? We cannot leave the stream in Project B because Project A cannot have visibility to Project B?
