Trainer Peter Moody says there is a chance Black Caviar might start in the Newmarket Handicap, but she would have to be "invited".
Moody said the "Makybe Diva treatment" - meaning an enticing weight - could put the Newmarket on the legendary mare's comeback agenda.
Black Caviar won the Newmarket with 58kg in 2011 and was weighted at 61.5kg last year but did not run.
Hay List, who has emerged as a shock Newmarket entry, won the famous sprint last year with 58.5kg.
Moody was only half joking when he said a Newmarket start for Black Caviar would depend on how desperate Racing Victoria and its handicappers were to have the great mare run at Flemington on March 9.
