Flinders Region route help

Hi guys,
I am starting into the Flinders next week and currently finish the planned route and was looking for any further ideas or comments:

1)
Adelaide > Nelshaby > Scenic Drive north (Telowie Gorge) > Port Germein Gorge east > Bridle Track west > Port Germein (Jetty) > Mount Remarkable NP West [Mambray Creek CG]

2)
> Princes Highway > Horrocks Pass east (Lookout) > Wilmington > Mount Remarkable NP east (Alligator Gorge) > Yapoona Springs Station {open???} (Mimbadoggie Ring Route) > Orroroo > Ridge Top Drive
Camping?

3)
> Carrieton > Mockra Tower Lookout > Horseshoe Rim Track > Quorn > Jacks Track > Dutchmans Stern CP (Summit Walk) > Warren Gorge

4)
> Argadell HS (Mount Arden Track) > Simmonston > Buckaringa Lookout > Hookina > Hawker (Yourambulla Caves)

5)
> Blinman Road north > Moralana Scenic Drive > Outback Highway north > Brachina Gorge > Bungeroo Scenic Drive > Wilpena

6)
> Hucks Lookout > Stokes Hill Lookout > Willow Springs HS (Skytrek)

7)
> Arkaroola Wilderness Sanctuary

8)
> Leigh Creek > Lyndhurst > Marree

9)
Marree > Mungerannie > K1 Line > Poeppel Corner

10)
> Birdsville and onwards

What do you think? Doable or too much? Maybe hair some days to more/less? Any highlights forgotten? Any unreal 4wd scenic places I missed?

Will the stations and homesteads already be open?

Thanks

Philipp
