alias xargs='xargs '

Then the alias expansion of xargs will in turn allow alias expansion of
the next argument.  (Except that you then have to also create
trailing-space aliases for all options you commonly pass to xargs
between 'xargs' and the final command name).

Sadly, xargs is one of the cases where shell functions won't help (xargs
doesn't execute the shell function).  Your other solution is to modify
$PATH to point to a directory under your control as the first thing,
where 'cat /your/ls' contains:
#!/bin/sh
exec /bin/ls --append-exe "$@"

such that your script then gets picked up by xargs, and you no longer
have to worry about aliases.
