What about a command-not-found hook of some kind?  E.g. any time you get
command-not-found, run function X with the command line as $@.  The only
rule would be that if you get command-not-found again while inside the
command-not-found hook, the hook is not called again.

Then one could do something like

realpath=($path)
path=()
setopt noglob
function command_not_found_hook {
  local -ah path
  path=($realpath)
  setopt localoptions glob
  urlglobber "$@"
}
