Yes.  The cygwin packet manager is not aware of your installation at
C:\TeX, of course.  But...

Please note that though the binaries for Windows and Cygwin have the
same binary file format, they are different.  You are quite brave if
you use binaries which are compiled for a completely different
operating system and I don't think that TeX Live should support such a
mess in any way.

According to the wget manual you can also set the *_proxy variables in
the (Windows) environment.  In this case you don't need Cygwin anymore.

That would be by far the cleanest solution.  If the proxy asks for
username and password, you'll have to provide a .wgetrc file.  I
don't know where wget expects this file, most likely in %USERPROFILE%.
