Cabal vs base

Hi, I'm interested in using Cabal to build the base library, just like any other library. Does this have any chance of working? How much work would it take? At the moment the libraries build script has broken on Windows loads of times, and if Cabal was used it would be nicer, less code, and more cross platform. I'd also like to compile libraries for Hat, Yhc and Catch, and if I can reuse cabal to do this that would be great. If this work was done, would it be possible to reduce the installation script for the full haskell.org libraries to get library, cabal config, cabal build, cabal install? So just a general question about what needs doing, who is capable of doing it, and what I can do to get it working. Thanks Neil
