Going back to the original intent of the OP, shared cockpit is a feature that i’ve been waiting for a long time.
Got some good news: In the last Live Q&A, they had announced that a team was going to work on the feature, with only some parts of the team actively working on it. They also mentioned the difficulty relied in exposing the network and sim variables to be shared, as well as reworking the network to be able to pass all that info. They did not provide any timeline for the feature.
If you feel like showing Asobo that we feel that feature is important and they should put resources into it, vote on the wishlist thread below
