Won't work because some systems, like shimano, don't overshift then center, like Campag, does. It relies on the next cog grabbing the chain and bringing it onto the cog. If the chain is too narrow, it won't shift, period.
PLUS, like unscented toilet paper, 9s is more expensive than 8s, 10s is more expensive than 9s..etc...least expensive compatible chain..got 10 cogs in back? Use a 10s chain, a well made, but inexpensive one..9s? 9s chain, etc..
