Former All Blacks hardmen Brad Thorn and Jerry Collins, plus league tough guys Frank Pritchard and Sam Burgess, are on the Fight for Life organisers' radar for the 2013 charity fight night.
"The guys on our absolute wishlist would be Jerry Collins and Brad Thorn," co-promoter Dean Lonergan said.
"We would love to have them in the ring.
"On the league side, we would take anyone who is of a big stature. This year we talked to Roy Asotasi, Frank Pritchard and Sam Burgess, who were all keen but couldn't quite do it.
"There are also other blokes who we would like to get on board, like Sam Thaiday and Petero Civoniceva."
Another high-profile league identity in the mix is Todd Carney.
Australian water skiing champion-turned professional boxer Lauryn Eagle fought in last night's bout, losing to New Zealand's Daniella Smith, a former amateur representative and winner of the IBF world welterweight championship as a professional.
And Eagle's partner Carney, 26, could step into the ring in 2013.
Lonergan said he understood Cronulla Sharks sensation Carney - one of the NRL's most gifted players - was "keen" to take part next year.
