I can't help but let the pessimist in me out and say "good luck". Why?
Consider how many engineers are unable to find even a little time to
"donate" to the code process to be aware of what is going on and review
proposed changes so that they can submit public comments during the
various standards public review/comment periods, I doubt that they will
find time to "donate" towards your very ambious, yet worthwhile idea. The
problem that you will face is that many engineers are more than happy to
bury their head in the "back of their cave" and blissfully ignore the
outside world (i.e. anything other than their immediate project).
OK...permissist mode off (for now).
