Cool question. Hamni handachiwaza, I dunno. I think I'm going to try it out tomorrow after class.
Standing up, the way I've learned shihonage is that your arms and body go in two directions so to speak. You step toward uke, but arms are deflected in the direction where uke was originally going. Ukes own arm serves to block a punch with ukes free hand, and if the whole movement is done well enough, uke ends up standing on the toes of their front foot, so kicking would be difficult (I've tried it). Hamni handachi though, I don't know if it's possible to get uke out of balance enough in this way. It'll be fun to try though, i'll post about it if we get any interesting results...
