I have a plan for my future wallet and notebook combo! This is my fairly precise sketch. See images below.
I'll give it a Z fold with wallet on one side and notebook on the other.
The notebook part will have holes in the middle at the top and bottom where I'll attatch two elastics for two small notebooks. I might make them into one tho.
The wallet part will have a zipper all around and for the inside pockets I'll use fabric to reduce weight and thickness. The curves on the paper represent pockets so I'll have two on each side. I'm going to attatch them with a W shape so that I get a proper pocket in the middle.
I'm not sure what to do about the fact that leather has a front and back tho. I'd prefer to not have two layers to reduce thickness and weight.
I hope this makes sense and is possible
