To be honest, I feel that SAT-AM/Archie characters have little chance in the video games without a huge backstory/appearance change. Meanwhile Sonic's brother Manic and sister Sonia have no chance due to mandates that they will not have Sonic have relatives in the video games. That said, if they WERE brought back they wouldn't be related to him in any way.

Characters from StC, Sonic X, Sonic OVA and Pre-Super Genesis Wave (Mostly Penders' characters) have no chance due to being owned partly or completely by different companies/people.
