My experience in the aerospace/defense industry suggests that this isn't really practical. Organizations that make aircraft and rockets and weapons tend to be incredibly conservative: they don't really innovate much. They have incredibly risk averse institutional cultures...no one wants to be the guy that decided to launch Challenger. I know of one aerospace company that occasionally has its rockets explode on the launchpad because they use battery designs from the 1970s that are known to explode with fairly high probability. They could easily get much cheaper much more reliable batteries with more modern designs but they don't because the exploding batteries "have flight heritage". This particular aerospace company is considered agile and nimble and innovative compared to its competitors.
