Those shots are easy shots.  yes, no problem.  Where things get complicated is with hdr timelapse or shooting changin light scenes like a sunset.  Manual mode wont accomodate over time, auto will make the infamous timelapse flicker.  Little Bramper was the only product I knew of that would handle these shots correctly.  but they are out of business.  Ever stuck a gopro on interval shots and shot a the sun going down?  It sucks!  Good for an amateur shot at best.  This will allow you to put the 2 axis head on the slider but it needs to be balanced very well as the linear bearing is a drylin and has play.  This will bind in movement and show with some jitter in the end product.  So i usually just use the slider with a camera directly mounted to the head.
