No bad consequences, but be sure that you calculate the overall ratio and don't just move the capstan line on the sharps to match the naturals in terms of key ratio. When you move the capstan you change the function of the wippen lever slightly. If you want to even out the SWR on a system that has different key ratios, you need to calculate out the entire ratio and put the capstan in a place that creates equivalency. Usually in such a system, the sharps key ratio is lower, i.e., gives greater mechanical advantage, so I don't worry about it. The shorter length of the key creates differences anyway that won't be addressed by creating exactly equal SWRs. One could argue, in fact, that because of the shorter key length, a slightly better mechanical advantage might be better. A lower SWR on the will cause a slightly deeper dip on the sharps but, in practice, I'm not sure it would be noticed.
