Seasiders boss Ince, a former Wolves player, has until Thursday to acquire the ex-Tottenham and Portsmouth midfielder O'Hara on a temporary deal before the window closes.
O'Hara, 27, has been frozen out at Molineux after being made one of the scapegoats following the successive relegations which saw them drop in to Sky Bet League One this campaign.
Boss Kenny Jackett, who confirmed O'Hara was training with Blackpool at his press conference on Monday, has been keen to start with a clean slate ever since arriving in the summer.
But while the likes of Roger Johnson and Stephen Ward have been sent out to Championship clubs on loan deals, O'Hara has been left kicking in his heels with the club's Under-21s.
He has impressed the Wolves managerial team with his attitude while there, though, and Jackett has introduced him off the bench twice this month.
Blackpool have been fighting a spate of injuries recently and would welcome the experience O'Hara would bring given Barry Ferguson is a long-term absentee due to an ankle injury.
