Well, there's an American Standard Glenwall, which has a bolt pattern that is 9" wide and 7.5" top to bottom. Are you sure that's not the pattern on your toilet carrier?
Here's the spec sheet: http://www.americanstandard-us.com/a...cSheet_901.pdf
Street price 500-600, depending on source.
The current Kohler Barrington models seem to be all floor-mount rear-discharge toilets. They don't hang on the wall.
The Crane Rexmont was the same kind of thing as the Glenwall, but I think it's discontinued.
The Kohler Odeon looks nice, but I don't think it's available in the US.
In short, I think the Glenwall is currently the only game in town for what you seek.
And most other wall-mount toilets these days for home use are models that put the tank and carrier in the wall, with only the bowl on the outside of the wall. Some are very attractive, like the Toto Maris wall-hung and Toto Aquia wall-hung (both of which also come in a standard, vertical-discharge, floor-mount version with a tank, so don't get confused; I'm talking about the wall-hung version of those models). Duravit makes a plethora of these kind of toilets as well, and Kohler, a little late to the party, also makes some of these, although models seem to come and go with them. But you don't want to open the wall, so these are probably out.
