Hickmott, who won the Melbourne Cup with Green Moon in 2012 and Almandin in 2016, both for seven-time Cup winning owner Lloyd Williams, had set Revelare for another 'win and you're in' race in the autumn, the Listed Roy Higgins.
But illness ruled him out of that contest and Hickmott had planned to target the Group 3 The Lexus Bart Cummings (2500m) at Flemington on October 4 as the gelding's chance to win his way into the Cup.
But after a pleasing first-up seventh at Caulfield before taking out a 2000m race at that track on August 30, Hickmott reasoned the rise in trip to 2500m on Saturday was the right way to go.
With weights due to be released on Tuesday for the Melbourne Cup, Hickmott said he may have to talk Williams about the best way for Revelare to get to the Cup.
"One of his biggest adages was trying to beat the handicapper," Hickmott said.
"We could cop another Group 3 win if he happened to win the Bart Cummings, but the next one's a tricky one.
"I'm not saying he couldn't win a Caulfield Cup but if he did and cop a two-kilo penalty, that's something that would have to come into consideration.
"I'll have a good chat with everyone and see which way we go."
