If NASM doesn't support macros etc, what about simply writing
a source pre-procesor to handle all of the oddities (and cope
with source control at the same time if desired)?

It seems to be silly writing a new assembler, and a preprocessor
is useful in its own right, as well as easy to create something
whose output can feed any of the common assemblers.

The same argument goes for C sources as well - rather than try
to hurriedly port everything simply produce a source preprocessing
program to generate C sources suitable for the main compilers, and
try to get all new sources to conform to gcc.

If many people will be working on bits of the code it seems sensible
to retain some source control system rather than none at all, and
even a simple preproceessor could cope with many of the systems
out there.  

Even better would be a true internet solution where anybody wanting to
work on a module locks the code for the duration of the edit and others
can see what is being worked on and why, as well as a history of
changes (in case we need to track down a bug). This is better than a
"free for all" scramble for the code!  I imagine a system where people
could cache the source on their own system, but to generate anything
other than their own personal hack have to submit a request
electronically, get some token to update the file, and have the system
check that their copy was the most recent at the start of the edit,
submitting the updated source only after some electronic checks for
validity.
