Wow, that's some ratio change!
yes, yes it is. Sometimes on my SINGLESPEED i will swap out the 46 front for a 32, and the 16 rear cog for a 20, so i can hit the trails locally, instead of the nice flat roads everywhere else when i commute. It requires the removal of a few links. No biggie, takes seconds and i enjoy working on my bike.
