No, not really. Diminishing returns. I've pointed it out elsewhere, but there's no stopping point for that approach. Make an accelerator that goes around the world. Dismantle the Solar system to make an even larger accelerator. Continue onward and use self-replicating probes to slowly convert, over millions of years, the Milky Way into another accelerator ring. Where do you stop? You can always do more until you paperclip replicator the observable universe into one big accelerator. Like I said, I advocate for looking for more clever ways to look for new physics, rather than bigger ways. And you must accept the concept that at some point we may have discovered all fundamental particles that can be found in the Big Baryon Bashers and that all accelerators after that are completely wasted effort, but we'd never know that, because we would say, "Well, we didn't find anything there. Gotta build a bigger one!"
