Druze state in Sweida is unrealistic
If the Sweida is split from Syria then Damascus will just go "OK pay your own salaries oh I will also block any aid and services from you"
Israel isn't going to do much since they are blocked by Dara and Huran region which is most Sunni Arabs who are loyal to Damascus, and Israeli incursion towards Sweida has to go through Darra which is is going to be costly and not worth it in the long run.
The only reason why it is easy for Israel to occupy quintra and not even all of it, is because quintra is mostly empty lands with few villages here and there.
Jordan has problems with drug smuggling from Sweida and sometimes they conduct airstrikes on Sweida, there is a possibility that both Damascus and Jordan will participate in Geo blocking Sweida from all directions, effectively making life more miserable to live there and Sweida has no national resources like the areas under the SDF.
