hmmm... my brain tells me it could work if your two ratios required exactly the same distance from BB spindle to hub.
Not easy!
Why would I need two specific ratios, my brain tells me that any two ratios would work.
Imagine the set up in your head with two very differing ratios, and imagine this to be correct and working - now mentally grow one of the chain rings by a substantial amount.
My imagination also forces me to also lengthen the chain to accommodate the larger chain ring.
