16 feet of head!? Wow, I didn't realize your sump was in the basement :-) The first step is to decide what flowrate you want through your sump taking into consideration how much flow our skimmer supports and how much flow your overflow supports and head loss. Just make sure your return pump does not flow more than your overflow. If your overflow supports more flow than your return pump, then your overflow will flow whatever your return flow is at.
Admittedly, it is a bit of a balancing act. If you are worried or uncertain though, just 'T' in a valve somewhere in the return line so you can flow some return back into the sump. This is handy for other uses as well so I would recommend doing it anyway.
I have never seen anyone with a basement sump that was able to use an in-sump pump as their return, although I am sure there must be some out there? Maybe? You may have to look at external pumps like the Dart, etc.
