As per suggestion in this post, consider dropping the RDF stuff altogether: https://plus.google.com/115203359751471044302/posts/92VKitpppB4
Of course, the RDF people would still be free to define their own algorithm, perhaps based on the current one. It makes sense for RDF users to decide what sort of microdata conversion algorithm works best for them, since they'll be the ones using the output.
https://github.com/gkellogg/rdf-microdata is the first non-spec converter that I'm aware of. It suffers from the conflicts that the ugly predicate URIs are designed to avoid, but if people want URIs that are nice to look at, that's what they get. If you drop the RDF conversion, don't forget to drop the ban on "http://www.w3.org/1999/xhtml/microdata#" for itemprop tokens.
FWIW, I think that it would be a good idea to drop RDF conversion for Microdata. Traditionally, the RDF conversion algorithm for Microdata has always generated really strange property IRIs for non-absolute-IRI properties. That is, the IRIs generated in the RDF conversion algorithm for @itemprop in Microdata do not meet the expectations of those working with all other data in RDF. This may help differentiate Microdata and RDFa enough to reduce concerns that the W3C TAG has around Microdata and RDFa.
