No,, because most (all?) touchscreen hardware can only sense a single point of touch. On the one I'm familiar with (Microtouch), placing two fingers on the screen gives a touch coordinate approximately midway between the two (but depending somewhat on the relative pressure applied to each finger). So on a touchscreen keyboard, any modifier keys (shift, ctrl, alt etc) have to be locking, so you touch the modifier, then the key.
