Good idea :-)

Please note that Tramp assumes to be talking to a Bourne-ish¹ shell.
All commands that Tramp contains are tailored for that shell.  It
doesn't make sense to change this to syntax, as is unlikely to be present on the remote system...

But _in that function_, only very specific commands are sent to the
shell.  Therefore, it _might_ work to use in that
function.  (But not in the other places.)

Tramp assumes to be talking to a Bourne-ish shell with all the
typical Unix utilities, eg, ls and cd.  So if you set all that up on
your Windows machine (using Cygwin, perhaps) and start sshd, then it
might work.

Well, it might work to use in
tramp-open-connection-multi, but it might fail to use in
the other places where tramp-sh-program is used.

That's why I suggested another variable.  Of course, I would document
things properly.  I could even have the new variable default to on Windows systems.

You could try a method which uses tramp-encoding-command instead of
tramp-encoding-function (similar for decoding).  That's the other
places where tramp-sh-program is used.


¹ Is that the right way to (funnily) say Bourne-like?
