Is there a way to decrypt, but not decompress ?

No, this is not possible.  The data is signed, then compressed, the
encrypted. To check the signature we need to decompress it.
Furthermore the compression protocol is partly OpenPGP specific.

Something like:

gpg <foo.gpg | gzip | send

should help.  Afaik, gzip is available for Windows and I bet also for
MVS or whatever you are running on the mainframe.
