an 8 or 9s same chainring should work. The correct separation should be built into the crank arm.
However, you need to be a bit careful because not all inner rings have the same offset, or distance from the crank arm face to center of the tooth. Too much offset will allow a narrow chain to jam between the chainring and crank arm.
