No tech - no prod.
That's it - you cannot produce components, you have no tech for, even with SM.
Technically some part of invader's specific techs can be reverse-engineered from captured components, if you capture enough of them, but I'm not sure if all of them are reverse-engineerable. It's very unlikely you can take all that techs from one or several captured ships, so I don't think it's easy to duplicate this design.
