This has been done.  Darwin 8.0.1 was produced in this way, and  
others (kito) have successfully booted an 8.2.1 build on ppc.

If it's twice as big, it's likely to be a universal binary instead of  
a single-architecture binary.  DarwinBuild's plists produce universal  
binaries by default.

In your build directory, you can use the following commands to list  
all the projects in the build (without version numbers), arrange them  
in a suitable build order, and then build all of the projects:

# darwinxref version '*' | sed -e 's/-.*//' > projects.txt
# /usr/local/share/darwinbuild/buildorder projects.txt ordered.txt
# /usr/local/share/darwinbuild/buildlist ordered.txt

Also, if you haven't already, you'll want to initialize your build  
directory with one of the plists from release.opendarwin.org, since  
those plists have patches that are required to make some projects build.
