I discover that this is a FO limitation too ;-)

I solved creating an extension to Saxon. I pass the nodes as
parameters and the exstimate the resulting heights programmatically
with Java2D and adopt a strategy to obtain a fit (including a font
resize if necessary). The extension return the final evaluated values
to xslt and here it is possible to use such values in
block-progression-dimension attribute.

It works fine.
