Central defender Bischoff though did have a spell on loan at Wolves earlier in the season, scoring the winner against Forest at Molineux in November.
Megson confirmed he is keen to bring in new faces before the transfer deadline, saying: "I am looking to bring in players all over the park. I want to bring in as many players as I can. I am trying week in, week out, day in, day out.
"But you have to make sure the ones you bring in are better than those you replace. It brings in that competition for places.
"Whether it will come about is another matter. The biggest issue is our league position."
