'fraid not.

I'm not sure if there's an official answer to this question, but I'm not
aware of any core maintainers that run Mercurial this way.  I've
certainly seen it suggested that you run it natively, if at all

No, TortoiseHg comes with TortoisePlink by default, but you can always
configure Mercurial to use the cygwin ssh:

ssh = C:\cygwin\bin\ssh.exe

That should work just fine, but why use zip?  A bundle would be much
more size efficient and more portable.
