Are the two objects interchangeable -- that is, can we swap A and B and get the same result?

Yes. We can swap A and B and get the same result.

over a hurricane downdraft and another over an updraft would result in different velocities

No, we drop them both over the Central Atlantic and then both will have about the same weather.

It's the same, unexceptional weather for both.

So it seems we can swap both the objects and the locations?

In your setup, if we take object A and lower it to the altitude of B, then take B and lift it up to the (former) altitude of A, will the object B reach ground first?
