It is six years since the veteran claimed the prestigious handicap when trained by the late Dessie Hughes.
He proved he was no back number when winning the Welsh Grand National at Chepstow in January, just days after officially becoming a teenager.
Raz De Maree has not been seen in competitive action since finishing 10th of 12 finishers in the Grand National at Aintree in April, but could return this weekend if there is enough give in the ground.
His trainer Gavin Cromwell said: “I think we’ll need plenty of rain rain for him to run, but there is some forecast.
“I think if the ground is right we’ll probably run him. He’s won the race before and it looks a good place to start.
“He seems in good nick.”
Raz De Maree was one of 23 horses left in the 100,000 euro contest at Tuesday’s forfeit stage.
The weights are headed by Alpha Des Obeaux, who could make his first start for Gordon Elliott after leaving Mouse Morris.
The Cullentra handler could also saddle Rogue Angel, who finished third in last month’s Kerry National at Listowel, as well as Its All Guesswork, Timiyan and Our Father. The latter has not run since finishing second at Cheltenham for David Pipe on New Year’s Day, 2015.
Willie Mullins, who won last year’s Munster National with Total Recall, has Montalbano and Steel Wave in the mix.
Other leading hopes include Black Scorpion, an impressive winner at Listowel for Eric McNamara, the Tom Mullins-trained Spider Web and Blast Of Koeman from Robert Tyner’s yard.
