Interesting refit Trev, thanks for posting it.
With regard to your chain sprocket dilemma, I think your rear sprocket is about as big as you want it, any bigger and you might run into ground clearance problems.
What you might consider to get a better than 3:1 ratio is to fit a lay shaft with, perhaps,a 2:1 pre reduction. This will give you 6:1 overall which should do the job.
