On-loan Manchester City full-back Wabara is set to play the final game of his current loan spell when Latics travel to Nottingham Forest in the FA Cup this weekend.
Derbyshire has already returned to parent club Forest from his own temporary stint and fellow forward Baxter sees his short-term deal at Boundary Park expire this month.
"The one thing Reece wants to do is stay," said Dickov. "He's told us that already.
"We're hopeful that we can extend it. We have to speak to Manchester City in the next couple of days.
"Reece is a big player for us. He's getting stronger, he's getting better with every game. Hopefully Reece, Jose and Matt Derbyshire, we can get them all back.
"I spoke to Matt on Thursday morning. He's got nothing concrete at the minute. He's openly said that if he can go and get something permanent and a bit of security for himself and the family then he'll do it,
but that's not come yet.
"He's also openly told me that if he's going to go on loan in League One then it'll be back to us so we just hope that nobody else wants him."
On Baxter, Dickov added: "The last conversation I had with Jose was that he wants to stay until the end of the season and that was a few weeks ago.
"There's been a lot of games and a lot of things happening over the last couple of weeks so other things are taking priority at the minute."
