Could/should the Mexican border be converted into a crossing-game, if they make it out alive, they are in?

Creating a realistic life or death crossing game - as you have probably already heard, things like making the fence electric, building a moat and stocking with live piranha, stocking the deserts with an overabundance of rattle snakes and land-mines, and quick-sand / trap holes, etc. If they make it past a certain check-point, they are in ?
