I don't see why not. Weight-wise it is similar to the OS 120. But the fuel tank would require some thought, because 1) the 150 fuel consumption would require something like a 20 oz tank -- and Saito fuel consumption is ususally higher than other 4-strokes -- and 2) such a large fuel load would almost require that the tank be mounted at the CG, which would in turn require a fuel pump of some sort.
