Duntle could try to put the record straight in Group One company in the Etihad Airways Falmouth Stakes at Newmarket's July meeting.
The David Wachman-trained filly was first past the post in her only attempt so far at the top level in the Matron Stakes, only to lose the race in the stewards' room at Leopardstown on September.
However, she has triumphed in both her races since then, the first back at Leopardstown in May before winning for the second year running at Royal Ascot with victory in the Group Two Duke of Cambridge Stakes.
"I have had a good discussion with her trainer, David Wachman, and he is very happy with the way that Duntle has come out of Ascot, so we will definitely have a look at the Falmouth," said Alan Cooper, racing manager to owners the Niarchos family.
"She has enjoyed the straight mile at Ascot twice so although the straight mile on the July Course will be new territory, it should be within her capabilities."
The Falmouth, being the first major clash of the generations for fillies and mares, could set up a clash with Sky Lantern.
The 1000 Guineas heroine overcame a wide draw to follow up in the Coronation Stakes at the Royal meeting.
"She has come out of last week's race OK and the Falmouth is on her radar, but it is too early to say if it will become her target," said trainer Hannon's son and assistant, Richard jnr.
Kenhope, who was a strong-finishing second to Sky Lantern last week, also figures among 35 entries for the Falmouth on 12 July.
Henri-Alex Pantall's filly is one of four French possibles along with last year's Falmouth scorer Giofra, from Alain de Royer-Dupre's stable.
John Gosden's Elusive Kate, just half a length behind Giofra last summer, may try to go one better after an encouraging reappearance in the Queen Anne Stakes, in which she was fourth to Declaration Of War.
