At its base description level, the ACA exchange is something that's been done before. What made it so complex was the sheer number of systems the exchange had to properly communicate with. But there were teams of people with enough domain knowledge to come in, figure out what the problems were, and fix them. I don't know if aircraft are the same. You might run into the problem that all the people who have the knowledge who could help you solve the problem are already working on the problem! Some of this stuff is so specialized and so different than what is done anywhere else that you won't get experience with it unless you do it.

I've seen this idea tried in the defense industry a number of times and it's not really successful.
