Putting aside the facts that illegal immigration is wrong and rewarding illegal immigration is also wrong and encourages more illegal immigration, do you honestly believe the illegals will happily "register", pay fines, and promptly leave the country after 3 years?
The plan is stupid at best.
Lots of things are wrong yet sometimes cops let people go with a warning or DA chose not to prosecute where common sense dictates.

Under this plan people who are already here illegally are not given any preference, indeed they pay a fine nobody else pays. That doesn't sound like a reward to me.

That's why we need a carrot and stick approach. The idea here is that given a legal pool of foreign labor employers will stay out of the black market and illegals won't be able to find work and will deport themselves. That requires enforcement of course, but there's still plenty of room for that in this proposal. In fact this plan would remove a lot of the pressures both external and internal to the bureaucracy that prevent enforcement.
