No, that's not needed. Tramp does its job for different target
architectures in different ways. For example, if the stat command is not
available on the remote host, it uses another implementation with perl
for directory-files-and-attributes, and so on.

ls-lisp does not support file name handlers, and Tramp uses it only
internally in case it doesn't know better. Support for remote
directories would mean to add a file name handler for ls-lisp - is this
what you have in mind? I don't believe it is necessary.

Best regards, Michael.
