British OpenOffice

Is there any way I can localize OpenOfficePortable to en_GB?
Or is the an en_GB OpenOfficePortable due out soon?
Failing that, how do I install my existing full-sized en_GB OpenOffice in PortableApps and get it to work?
Also how can I reduce the full-sized en_GB OpenOffice to a more portable size?

I have read other posts on similar topics and followed their advice and they don't work for me. I end up with a massive openoffice folder in the OpenOfficePortable folder and no links on the PortableApps menu. I have tried moving the OpenOffice executables out of OpenOfficePortable/openoffice/program folder and into the OpenOfficePortable folder but although the links show up on the PortableApps menu they don't work when I click on them. I am using OpenOffice.org 2.0.2
