Oh, no, that won't be a problem, because eshell-tramp-initialize has to
be called (for each buffer) to register the functions.

em-tramp.el line 51:

  (make-local-variable 'eshell-complex-commands)
  (setq eshell-complex-commands
        (append '("su" "sudo")
	        	    eshell-complex-commands))

So if the module is enabled (and loaded, of course), and you disable it
and then create a new eshell buffer, running the commands su and sudo
will invoke the external commands, not the internal eshell/su and
eshell/sudo.
