You can modify the variable `auto-save-file-name-transforms' to replace
the leading part of the path to a value which suits you. Besides, you
might want to do something about the further slashes.

By default, Emacs comes with one transform defined for remote files
(whose auto-saved twins end up locally). Perhaps you can reuse this,
if it suits you.
