Well, as someone else has said in this thread, if you're doing it for fun, or
to learn more about memory management / file systems, etc, then got for it. But
I wouldn't expect much of it to be included in the official versions - you've
got to remember we're dealing with a relatively tiny address space, and the
extra overhead in the kernel would significantly reduce the max size of user
programs / data.
But if you get anything going, you should probably create patch files which can
be posted on the sourceforge site for anyone interested.
