I don't think anyone tried that.

One problem you might bump into is that building Emacs requires to
actually run Emacs you've built, and also lib-src/make-docfile, which
are not Cygwin programs.  If the Cygwin shell invokes them with
Cygwin-style absolute file names, these programs might fail, claiming
that files don't exist.  That's exactly the problem that MSYS attempts
to solve; it is otherwise just a fork of Cygwin.
