Darren Till has named a five-fight wish-list which includes Carl Froch and Jake Paul.
Till is coming off a valiant decision victory over fellow ex-UFC contender Yoel Romero in the Bare-Knuckle Fighting Championship.
But having crossed from MMA into traditional boxing and now into the gloveless version, Till is keeping his options open for new opponents across the disciplines.
"If Carl wants to sit down and organise a fight for March in Nottingham or [the AO Arena in Manchester] I am willing to travel to Nottingham next week and sit down with him and organise it," Till posted to social media.
"If it doesn't happen around March I'll stop chasing it for the foreseeable."
Former world super-middleweight champion Froch is now 49-years-old and hasn't boxed since knocking out George Groves 12 years ago.
Froch has previously responded to Till's call-outs. Last year he said: "When you're a four-time world champion, unified, and a Hall of Famer you don't worry about people like Darren Till."
Till also posted to social media: "After Carl I will pursue the Jake fight. After that the [Tommy Fury] fight or [Mike Perry] fight then I'll finish with [Lorenzo Hunt] for 2028. I like this plan."
Till has previously claimed he was close to agreeing a deal to fight for Jake Paul's MVP promotion before signing with BKFC. Ex-YouTuber Paul, who most recently lost to Anthony Joshua under traditional heavyweight boxing rules, remains a key target for many fighters in the crossover fight scene.
Mike Perry is a long-time rival who didn't cross paths with Till in their UFC days.
Till had been scheduled to fight Tommy Fury, the brother of Tyson Fury, in a boxing match. But the fight fell apart after a fiery news conference where Till threatened to break the rules and kick his opponent.
Lorenzo Hunt holds the ironweight and light-heavyweight titles in BKFC. He went face-to-face with Till after the Liverpool fighter's recent win over Romero.
