Let's throw caution to the wind and imagine that Trump gets a better Wall than he ever imagined, even in his wettest of dreams. Fifty feet high, twenty feet thick, machine gun emplacements along the top, and fronted by a 100 foot wide moat, chock-a-block with perpetually pissed off crocodiles. A Wall that is unclimbable, uncuttable, and un-dig-underable. Such a barrier would have zero effect on illegal immigration into the US. Why? Because you've got tens of thousands of miles of border that AREN'T walled off.
Clearly, people are willing to form caravans and travel 1500 miles or more in order to get into the US. Some of these poor sods even go to the extent of paying coyotes to sneak them across the border - I've read that $2000 per head is the going rate, more for kids. For that kind of money, you can obtain a set of false identity papers and boat passage into the US (there's some evidence that drug cartels are already providing this service). For a little more, you can get the papers and a flight to Canada, then enter the US.
So, unless you plan to wall off your whole damned civilization, this is an idea that goes nowhere.
