Not a bad list at all, Ron. I, for one, could certainly live with it without any qualms. However, since we are dreaming a bit, here would be my choices:
I would choose at least two just as you would, Ron, one in 12 and one in 20, and both would be pumps. Given my druthers though, I would also add a good 12 gauge double SxS as well, preferably with a 20 inch barrel.
A good .22 auto, probably a Ruger Mark II or Mark III, and preferably with a bull barrel.
A .22 revolver should definitely not be left out. My choice would be an S&W Mod 617 in stainless steel with a 6" barrel.
For an automatic, I would also want a .45 1911 pattern pistol available, but also a good auto in 9mm, probably a Glock 26, or possibly, a small-frame H&K.
For a revolver, I would also want at least two. One would be a K-frame .38/.357 with a 3 or 4" barrel, preferably a Smith. The other would be a Smith 29 or 629 in .44 magnum with a 6" or even longer barrel. If at all possible, I would also want a snubbie in .38 Special, likely a Smith 37 or an alloy frame637. Hard to beat a snubbie for concealed carry with light clothing, I think.
For a rifle, the choices become a bit harder. I would definitely want a bolt action, scoped, Remington 700 in .30-06. I would also choose a good lever action, like the Marlin 95, in .45-70, with iron sights, preferably of the aperture type. I like peep sights.
If I could have one more heavy caliber rifle, I think it would be a bolt action in .375 H&H, preferably one built on a Mauser action. For a .22, I would likely go with a Ruger 10/22 with a scope, and/or a Marlin lever with iron sights.
