They should have blipped Rhodey (War Hammer)

It would have been interesting to see the armor just collapse, empty. And (spoiler for Endgame) Bruce is too important to the next movie for it to be him.

Although come to think of it, other people's clothes turned to ash, so maybe the armor would too? They should have had piles of empty clothing everywhere anyway. Would have been a fitting image of what was lost, in addition to making more sense.
