I have a series 3 carbon fiber tripod...

About to take on a large copy work job and think I need one of those lateral arms to move the camera out far enough horizontally so that the legs are out of the way when I am shooting with the camera pointed straight down....

1. Did they ever make a carbon fiber version of the lateral arm for this tripod? (GT3530S)
(i can see a few aluminum ones for sale on ebay but no CF anywhere)

2. it looks like gitzo also made a (very expensive) right angle bracket, which in theory one could just use in conjunction with a second CF center column (also $$$)

3. Does anyone have experience rigging up a temporary sort of copy stand like this and could offer any tips? My idea I guess is to get the used aluminum arm and a tiny ballhead, set up some strobes with softboxes for lighting, throw a few sandbags on my legs and just run and gun....
