I would do Simpsons Gap - Jay Creek - Standley Chasm via high route - Brinkley Bluff high camp (carry water) - Fringe Lily Creek (water 10 mins downstream) - Hugh Gorge with side-trip to Hugh Gorge Waterhole - Rocky Gully - Ellery Creek South.
This assumes your party are OK with carrying a five-day pack, plus water for Brinkley Bluff. It would be normal to leave a food drop at Standley Chasm so that you don't need to carry food for 7 days from Simpsons Gap.
The last two days across the plains are less interesting, and if you are OK with a long day you could skip the overnight stop at Rocky Gully.
You could add a stop at Fourfive Junction if you like.
I haven't actually done this itinerary. In 2018, I did Simpsons Gap - Jay Creek - Standley Chasm via high route - Brinkley Bluff - Fourfive Junction (shortish day) - Hugh Gorge Junction with side trip to Hugh Gorge Waterhole - Bush camp between Ghost Gum Flat and Rocky Gully (carry water from Hugh Gorge) - Ellery Creek South.
In 2021, I did Ellery Creek South - Rocky Gully - Hugh Gorge Junction (with side trip to Hugh Gorge Waterhole) - Stuarts Pass (water carry from Fourfive Junction) - Standley Chasm - Jay Creek - Simpsons Gap.
I hope this gives you some ideas. My only real recommendations are to include the side trip to Hugh Gorge Waterhole (adds 1 hour), to take the high route between Jay Creek and Standley Chasm (adds 1 hour), and to do a high camp on Brinkley Bluff if weather conditions permit.
Standley Chasm has showers and a cafe, but if you don't want to camp amongst cars you could replace it with an overnight at Millers Flat (water in puddles/spring in the Creek upstream, will need treatment, or you may find good water in Mesic Gully on your way down from the high route).
