Yes , Possible
In the following order in my opinion..
Isb-Muzzafar abad-Domail (Kashmir)-Mansehra (One Day must)
Chillas-Raikot Bridge-Fairy Meadows-Raikot Bridge (Can be in a day but it deserves more days)
Raikot Bridge-Chillas-Astore-Rama ( Visit Rama meadows , Rama lake) (One day is must, rest is upon you)
Then to Rupal and Minimarg and after that head-towards deosai and then skardu(Satpara Lake on entrance to skardu). From where you can come back to gilgit and then can go to Sost(Pak-China Border).
8-10 days are enough.
All of the areas can't be accessible through your High roof. Better to go local.
