I would actually prefer if Black Siren was on the Legends. They usually have villains on the team. (Mick, Snart) They have a different moral ground than Team Arrow and Flash when it comes to accepting that. Oliver and Barry weren't going to have villains like Mick on their teams, but they won't be pestering Sara throughout crossovers about it. There is a difference between them allowing the Legends to do stuff and them doing the stuff that the Legends do.

Also having two fighter characters on the team with bowstaffs would not add too much. With Black Siren, you can have a friendship with Mick. A dynamic between Sara and Laurel-2. Possibly some other ones like if Black Flash returned and she was put in a similar situation to Eobard due to being afraid of Zoom. Point is Team Legends would accept her before Team Arrow would.
