Capcom aren't miracle workers. They had a deadline like everyone other game developer. They just chose to create new content instead of rehashing old content from an outdated system (outdated as in 2003).

They couldn't have possibly revamped every monster from MHFU and made all 13 weapons for all of them given the development time.
