Trainer Mark Johnston originally named Thursday's Sky Bet Lowther Stakes at York as the next calling point for Nyaleti after she swept to a five-length success in the Group Three Princess Margaret Stakes at Ascot last month.
However, Johnston has shuffled his pack with impressive Goodwood debut winner Threading now supplemented for the six-furlong Group Two on the Knavesmire.
"With Nyaleti, the plan was the Lowther, but we want to win a Group One and the Morny looked a possible," said the Middleham handler.
"It was well publicised last time that Ryan Moore said he thought she'd be better over seven furlongs and I wouldn't doubt his opinion at all, but she has got lots of speed and is clearly well capable at six, there's no doubts about that.
"She's a very big, strong filly, very straightforward at home and we don't really have to do much with her."Nyaleti is one of three Yorkshire raiders in the French Group One on Sunday
Nyaleti is vying for favouritism with French challenger Different League, who won the Albany Stakes at Royal Ascot.
Nyaleti is a best-priced 3-1, while Different League is 5-2. Karl Burke's raiders Havana Grey and Unfortunately are 9-1 and 11-1 respectively.

Elsewhere Shutter Speed is set to run in the Juddmonte International at York on Wednesday after being a late withdrawal from Saturday's Prix de la Nonette at Deauville due to rain-softened ground.
The John Gosden-trained filly won the Musidora Stakes over the course and distance in May and will now give her owner, Khalid Abdullah, a runner in the Group One feature he sponsors.
"The ground has come up too soft in Deauville. There's been rain around and there was rain again this morning, so we've diverted her to the Juddmonte," said Teddy Grimthorpe, racing manager to Abdullah.
Shutter Speed has been absent since finishing a close fourth in the French Oaks at Chantilly nine weeks ago.
