I think chain line with the inner ring would be preferable to outer ring only. I'd prefer not to run a chain guide. Is this risk worth any thought?
I would think chain drop would be a significant risk. If you go to all this trouble and even shorten the chain, imagine how bummed you'll be if you drop the chain anyway.
