The first Ironman suit was built by taking components to from (probably) multi-million dollar missiles, many other comments provided by an overly rich asshole benefactor.

And that’s ignoring the ongoing costs of maintaining the suit, or R and D on new suits, nor the costs of liability and litigation when you fuck up and accidentally murder an innocent.

So no. It’s not even close to a possibility in any context where reality can’t just be dealt with through handwaivium.
