Its not "a few other", its "many other":  link-grammar lists 637 of these adjectives.  Not all of these comparative imply "more"; many imply "less" or, at least, one end of an ambiguous scale: "abrupter" (less polite) airier (less down-to-earth) ashier (less healthy) badder (less good) baggier (less well-fitting) balder (less hair) baser (less educated) battier (less sane)   So adding "more" seems like the wrong thing to do.
