[MCU] Remote use of the Infinity Stones (Possible Endgame Spoilers)

We have seen that Tony Stark can remotely control his armour as if he were there using varying degrees of immersion. Now we have seen that Ultron was able to use the Mind Stone directly himself and The Vision has one embedded in his construction that he is able to use so this strongly suggests that the Stones can be activated by machinery, or at least machinery driven by an intelligence be it a sophisticated AI or a living being. With this in mind, could Stark have used the Stones safely and from a distance using his armour remotely, or alternatively could he have allowed one of his empty suits to be controlled directly by F.R.I.D.A.Y. as we have seen J.A.R.V.I.S. do previously to carry out his instructions?

Trying to avoid the cost of using the stones... not gonna work. The user has to use the stones either in hand (bad idea unless you're sufficiently powerful) or by some tool/conduit (a hammer or a gauntlet of some kind). Vision and Ultron used a single Mind stone, so we aren't really sure if all stones can be used like that. 

The stones will incur a cost to the user if they use all simultaneously. Can't circumvent it. Either the stones won't work or they will remotely fry you if you succeed. Single stones can be contained and manipulated. The collection will not yield so easily.
