No, Va is a function of whatever the manufacturer chooses.
The only time Va is a function of stall speed is if the manufacturer decides to use Va min as the design Va.
There is no airworthiness design requirement for Va to have any relationship to limit load, or perhaps you can point to one.
There is nothing to stop a designer selecting Va=Vne
To try to put the long held Va myth to bed the FAA found it necessary to use a new speed - Vo.
