Hendry picked Quade over Sandberg for the manager's job but left the door open to the Hall of Fame second baseman as to whether he would return to the Cubs organization.
"[Having Sandberg join the staff is] not impossible, that's for sure," Quade said on WMVP-AM 1000 on Wednesday. "That would be a unique circumstance, but I'm telling you, everybody is on the table.
"I would never say anybody is not available," Quade said. "That would be a unique situation that Ryne and I would have to talk about. And look, by the way, he's got other opportunities from what I understand. It's not [only] what I want, necessarily, he's got a lot of things to deal with as well. But we'll have to see."
Pitching coach Larry Rothschild exercised his option to return for 2011 and hitting coach Rudy Jaramillo has two years remaining on his contract with the Cubs. Both are expected back.
Sandberg was the Cubs' Triple-A Iowa manager, leading the team to a first-place tie and an 82-62 record. It was his fourth season as a Minor League manager.
"Ryne Sandberg, as great a player as he was, he's just as good a human being," Hendry said on Tuesday. "What he did going to the Minor Leagues and the way he carried himself was very, very good. I think [Cubs chairman] Tom Ricketts and his family are very aware of how important it is for 'Ryno' long term to be a member of the Cubs family.
"[Sandberg] is disappointed [he didn't get the Cubs job]," Hendry said. "I'm sure like a lot of people, you feel like your heart is set on that. Over time, I hope he's a Cub in some capacity forever."
Asked if he would welcome Sandberg back to the Cubs, Hendry said, "Absolutely, absolutely."
Sandberg has said he would consider other big league managerial openings.
