Nope, definitely not nuts. Donor files are a really great invention - kind of a surprise that nobody uses them much. I've been meaning to write Dan Wilmes and ask if his next version of CR2Edit can include making Donor Poses. After reading some things Jaager posted, I wrote a how-to for my P4FemMagicTrio pack - it's really not hard to hack the files by hand, but gets tedious. I'm betting Dan could turn it into a button push!
