Can Xenon weapons be produced using Xenon build methods?

[Raptor34]

So apparently creative starts allows you to start with F/B/H/PE/SE blueprints which from what I understand is not possible normally? Those ships are constructed using Xenon methods, i.e. using Ore and Silicon along with ECs.
Unfortunately, or maybe it's because I haven't done the research yet, it seems that you cannot build their gear out of Ore and Silicon. Do I just need to do that thing where the Xenon drop the thing and I research it to unlock that? Or is it just that you can't normally get those ship blueprints anyway and so they didn't plan for them to get built out of hull parts?
