I think it's possible but not feasible.
For FQ, you'd take a left at Vacation Club way, cross the canal and walk into the grass along the canal after you cross it following the canal. You'll have a small amount of trees/bushes to get through as well and then you'd be at the path along the canal for FQ.
I personally would not do either for a number of reasons including that neither are acceptable to Disney but I also wouldn't do THV or OKW without a car.
