In A Sign and Trade, Can Signing Team Include Another Player?

I thought I knew the answer, but wanted to double check.

When a team has an unrestricted free agent, and wants to sign and trade him to another team, can they include another player on the team to match salary for the player they are getting?

Example, they want to sign the unrestricted FA Player 1 on their team for 10 million, and then include Player 2 who is making 5 million, and send to another team to get Player 3 who is making 15 million.

And do salaries still need to match if teams are over the salary cap, or if they're over the luxury tax cap?

Multiple other players and teams can be involved with a S&T deal. They are usually kept relatively simple as just being a S&T deal makes it more complicated as the player(s) being signed also have to agree, along with all the teams.

The only difference with a normal trade is that the team receiving the signed and traded player is then hard-capped at the apron for the rest of the league year (July-June).

Salary matching is obviously needed above the cap (though if a team has cap space then they can obviously take extra salary back into it).
