After having had a closer look at the dependencies I think changing the revision number would not be a good idea because some packages depend on one exact version of another package. Of course I could adjust the dependencies of all the packages I changed but then I'd also have to repackage other related packages just because of the dependencies while they technically work fine and I don't know where that would end.
So I'd suggest we stay with the current set of packages and just set them on hold.

Edit:
I just completed the pulseaudio instructions in the wiki article.
