Depends on which model you're asking about

I guess I'll just go through all the ones since the yellow jacket
Shoes-I don't think so
Bahamut BL- No diagrams but a cp is on Kamiyas website. (just search Bahamut BL origami and you should get it)
Chameleon- Diagrams in VOG 2 (I don't have the book but it says that some form of instructions are in the book)
Bison- Its a recent design so probably no
Praying Mantis- No but there is a cp. Seeing as you've folded a 3.5 it should be a piece of cake though.

His photo stream also has a cp for a newer better (but also far more complex) mantis and two flying mantis cps.
If you do consider doing this, you should probably use single tissue or double tissue. Most other papers will end up too thick to do thin legs.
