Hey TheGreatGasMaskMan
While I have never developed KodaChrome II in Caffenol, I have processed a wheelbarrow of other films both color/c41, chrome/e6, BW expired and fresh in the magic soup. Go for the old school teaspoon/tablespoon version of the recipe, and start off with 20 mins. Do a pre-wet water bath at 68ºF and then process the film. I'd process the plus x the same way ... **
Do you have a handle on the ingredients you will need? One of the biggest problems with Caffenol is people can't find the right ingredients so it screws things up. feel free to PM me if you have ?s
Good luck with your experiments !

** feel free to get exact measures if you are making 1L at a time, from my entry in the Caffenol Cookbook. I have never found it necessary to actually measure the ingredients, and just eyeball the amounts.
