We have something similar with dpldocs which builds docs lazily, 
and is now linked from code.dlang.org

It's a matter of extending it with downloading toolchain and 
building.

I can't speak for anyone else but it looks to me as a realistic 
way to have it.
You can also donate to Adam for http://dpldocs.info/, it has 
interesting things like cross-package search (search ALL of 
code.dlang.org at once)
