I think the damage to the bud would be too severe and the bud would die. I'd just top it (then try to root the cut top for my next grow:thumbsup and let the two top lateral shoots become the top buds. The top bud of a plant puts out a hormone, auxin(?- It's morning and I'm not quite awake yet) that keeps the other side shoots from "wanting" to be top bud. When you top, no more auxin and there is a "free-for-all" to be top bud. Your two top lateral branches usually grow like your normal cola bud- big and fat! So just top and you'll get two colas. - Granny:hippy:
