Well, you'd need to find a team that desperately needs all three of those players (a soft but gifted second-line center; a tough but injury-prone and mistake-prone 2nd pairing d-man with a cannon of a shot; a 1a starter).
If you find that team, they must also have what you need. They must also be willing to give up that top d-man (and due to Souray's impending free agency, and the fact that the package amounts to scraps, I wouldn't count on it).
On top of all that, it'd have to make "cap-sense" for both sides. You're asking a team to take on about 5.5 million in salary.
Right now, it makes most sense to keep all these players. Ribeiro can potentially be very good centering Samsonov and Kovalev, Souray is a big part of this team on the ice and especially in the locker room, and with an unproven starter like Huet, it's good to have Aebischer push him in training camp at the very least. Keep them until something good becomes available on the market, no pressure on Gainey at the moment to trade any of them.
