Toto makes models that will convert to a true 10" rough.
They come with a standard 12" kit, but the 10" kit can be ordered.
That pushes the bowl forward 2" away from the wall.
They work with rough-in's that are as close as 9 1/4" from the wall.
The water supply needs to be at least 7" from the center of the shutoff, to the center of the fixture or it will hit the back of the toilet.
The model pictured is the Vespin
Toto also makes a CST703.10
that uses a 10" bowl and standard tank.
According to the pdf, it looks like it will rough in at 9"
