Sure, theoretically, if it could come to an agreement, and meanwhile the cross-border cooperation of even the inter-EU countries is at an abysmal rate, and currently, even during a goddamn land war with Russia, Germany and France can't come to an agreement to build a fighter jet ensemble (together).
This is unfortunately the problem. The level of the public debate is abysmal, most politicians push unbelivably stupid shit about immigration and other identitarian nonsense, budget gets spent to ensure cheese and wine have the proper AOC certifications on them. Honestly up to a point I even understand it, many people don't see themselves as having a meaningful identity as EU citizens and you can't force it upon them.
Asking for sensible AI policy is like asking for a base on mars.
The fighter jet program was a jobs program, not dissimilar to how many US government programs are jobs programs by having different parts of it made in different states for no goo reason. Add in some nationalism and it was inevitable it would not work out.
In a weird sense, the EU exemplifies what the USA would be like without a strong federal government: Dysfunctional as states compete with, undercut and stifle each other.
You mean like they've been doing since the 1950s with the the largest physics laboratory in the world (CERN)? Or more to the point, the European High-Performance Computing Joint Undertaking (EuroHPC JU) of which 27/27 EU member states participate?

Even at the smaller level the ethos and ambition is clear - take EURO-3C: the Horizon Europe project aimed at delivering a pan-European sovereign infrastructure that integrates Telco, Edge, Cloud, and AI capabilities under a federated model which has 70+ Euro-participants.
