DMW-CMC1 on Panasonic 14-45mm lens

I recently purchased the Lumix G5 camera and occasionally use the 14-45mm lens from my IR converted G1 on it. I would like to start trying some macro photography without the expense of buying a dedicated macro lens. Can't find any information on whether Panasonics new macro converter (DMW-CMC1) will work with the 14-45mm lens. Panasonics website only lists the 14-42mm as being compatible, but I can't see any reason it wouldn't work with the  14-45 also? Anyone have an answer. Thanks.
