Whew! Talk about prejudices!
Well, yeah, I always knew you were prejudiced against double rifles, Bill (I know, the double triggers DO defeat a handful of people), and I appreciate the candor, but there's really no need to observe the obvious.

The end of the barrels on the Chapuis 9.3x74R are thin where most of the weight reduction comes from. Though I'm not up to stuff on my cylinder stress calculations, it is not far-fetched that the barrels on a 470 or whatver could be just as thin, from a strength standpoint.
Of course they can, and it isn't far fetched at all. In fact, it's been done for a loooong time. The Chapuis barrels ARE thin. I measured two at DRSS last January. Min wall went .078" and .079". A good friend's 1928 vintage Holland .465 measures .086". That rifle weighs 10 lbs, 12 oz. The owner is 75, and just got back from 25 hunting days in Bots with it, where he got a 70 pounder. Loves the rifle and was thrilled with how well it worked out for him.

The pressure of a 470 and a 9.3x74R are no different
They're quite different, but...

so why not have a lightweight 470 or 450/400? If one can take the recoil abuse, why not?
Look at it realistically. For makers like Heym, Merkel, Chapuis, etc., why should they shoulder the cost of setting up to build a 9 lb .470 that will appeal only to a handful of tools who want to be crash test dummies? They can't afford such nonsense and still keep their prices within their market niche. Most Heym .470s come in at 10 lbs, with the Merkels at 10.5 or so. Look at how many of those end up with a pound of mercury up their butts. The makers know that, and realize that it's a pretty good indicator that they're already pushing it as it is.
Why give a .400 the extra recoil and recovery time of a .470 by building it underweight? Likewise, why turn a .470 into a .500 in every sense except power?

I guess everyone is different but the 410 double shotgun feel to the 7.3 lb. Chapuis 9.3x74R can hardly be compared to a 10+ pound 470.
Who made such a comparison?

Even John Taylor several times said to the effect that doubles were obese.
Untrue. In fact, Taylor wisely pointed out that it was a mistake to build them too light.

(this should get 400 NE going!).
Come now William, we both know that if a pound of gun weight makes that much difference to you at the end of the day, you're either too old for the activity, or you just need to get in better shape.
