Yes, that's the one thing I wasn't able to add before the battery on my pocketpc died earlier today. I do believe it will work, but you shouldn't put too much tension on the chain. I was also going to add that maybe you can still make something to screw into the end of the existing shaft to fill the empty void in the outside sprocket which will help things a little.

And I too am curious as to what that little peg is in the hex portion of the shaft in that AM photo.
