I haven't started to port my website to mambo yet, right now I am testing the applications (gallery, coppermine, zoom gallery, guestbook & etc) that I want to use for my website in conjunction with Mambo and SMF, I am looking to start around June, July.

That said what I Really would like to see is instead of Mambo registration, SMF Registration why cause I have a custom SMF registration page (First Name, Last Name, Location, From To year was in college, Bio* option) that I would like to use instead of Mambo’s, I am not a coder in-fact when is comes to coding I am clueless after about 6 to 8 weeks of struggle asking in different forum trial and error I managed to make the custom registration page I don’t want to start all over again for Mambo hence a request for SMF registration page.

It could be an option in Mambo-SMF configuration page select whichever one user requires.

I am ever ready to donate

I think that's a very good roadmap.
The only thing I can think of, is to _maybe_ have an option to replace smf's wysiwyg buttons with the wysiwygeditor chosen in Mambo.
This way users will face one common interface when contributing something.
