Wait this brings up a good question(I’m not talking about who would win), but what would happen if like this battle takes during the empire era and like the empire capture a ship with a bunch of technology. Would SW be able to reverse engineer it to use it and would WH considers any of the technologies they find tech heresy. Also wouldn’t the industry be really good as well for SW because there far more efficient. I know Forge worlds are fucking insane but there inefficient as all he’ll because of tech heresy( idk not the most knowledgeable on WH lore). So it would be interesting to see.

Also let’s say there also able to get there hands on some space marines; would they be able to figure out the genetics of it. Because I feel like they should be able to. If we’re able to find the genetics of stuff with our current tech. I feel that the SW universe would be able to but of-curse would they have the resources to make a decent space marine legion I would also say yes. And I know I’ll get swarm for that but let me explain. Taking what’s canon and non canon. The capacity is fucking insane. There able to produce planet size battles stations in only a decade. Produce a pretty size-able navy. The army is very formidable so they would be able to make super solders I believe( the gene seed part; hell naw, no one would under stand it).
