Are you implying that someone would be confused by this happening? or is your concern that someone might be wanting to use the mouse in one hand and the touch screen with the other hand?

I'm more concerned about the behavior & feedback from the system. It's not just a matter of "track the cursor to where the finger touches" because in truth it's dealing with multi-touch (all those pinch, zoom, swipe gestures) vs a single curser location & a click.
Did you ever get a chance to try out a first generation BlackBerry Storm? It was essentially what you suggested "replace the 'click' with a 'tap' instead" and it was terrible. Of even if you ever used windows XP on a smart board, it's just not a great experience.
A mouse cursor always has a position on the screen, even if you don't touch the mouse for 10 minutes the cursor has a position, wherever you left it. But with a touch screen that's not the case.
