"... and the prototype product of the machine is competing in the Vytal tournament just now - ooops I forgot to tell you, Ozpin, no offense intended"
That's a little bit speculation on my side, but it fits the scenario. You do not have to spill out classified information, to reinforce a claim that has already been accepted. Is anyone in the group forwarding any doubts concerning the chances of success? The weakest you get is a "believe" which I would set at at least 70% chance of success.
There is no doubt and to get around that, you can pull
(1) group dynamics (because it would be so convenient to work, they believe it and reinforce each other in their beliief. like a group of moron mountaineers seeing dark clouds gathering but marching on to the summit stating repeatedly that they will make it). Narrativewise that should lead to something bad happening because of proceeding, which it wasn't.
(2) cheating Pyrrha by omitting important information, like that the chances in general are not on the level of "we can", but rather on "we try". This should result in them being busted and punished (at least them who know better), did also not happen (at least until now)
(3) The machine is decoration for Pyrrha's conflict and it simply does not matter if it works or not, because the writers do know that the process will be interrupted. As such it will never be brought up again, holds until now
(4) The machine is a decoy to divert attention from something more important (like Vernal flapping arms, while not showing flame eyes). I have no idea what the hidden thing could be.
It is higly unlikely that you would try something with shit chances of success (e.g. 20%) on such a valuable "ressource" as a maiden. There is no talk about "theoretically", "will it work at all", "enumeration of possible outcomes" - before the "occupied" problem.
This is just my opinion, but having two methods of aura transfer would be a little bit decadent, what would be the point of "Aura transferred but not with this machine but with magic, another machine or a semblance".
You have a machine which is described as being able to transfer aura. There is no explicit doubt about this capability. The description heavily hints that the original target was "something" in contrast to "someone". The machine was designed in Atlas.
You have a robot with an Aura from Atlas.
This is almost a hint orgy, which in fiction often means indeed decoy.
