Rucker61,
Yes, it would be a logistical nightmare to deport all illegals according to the plan you have laid out - due to the number of illegals involved. However, if the number were reduced, I believe it would be feasible.

To reduce the number of illegals needing forced deportation, why not employ plans that increase "self-deportation?"
We can do this by decreasing the jobs available to illegals by actually prosecuting employers of illegals.
We can cut off welfare benefits to illegals.
We can cut off public services to illegals.

If we make it hard to be an illegal alien in this country, most will go home/elsewhere.
Those that remain can then be rounded up and deported.
Rounding them up is simple, just have an "Illegal Alien Civil Rights" rally, and 90% will show up wherever you like.

BTW: This will never happen.
