I spin a bit faster with shorter arms, 5 rpm from 175 to 172.5, although it took me a long time to notice as if you just switch you will try to keep your old cadence. Some would argue that being a spinner helps. On the other hand, as I don't know your body dimensions I can't really speak about what will happen to you.
All of this may be the reverse obecalp effect. In all honesty, it probably won't matter one bit.
