We have de facto amnesty right now. So the status quo is amnesty. There will be another amnesty no matter what. Removing 11 million people isn’t practical. That’s the political reality. That’s the loaf of bread we have to work with.
What items are absolute for conservatives? I’d say a tight southern border, no welfare for illegals (blacks would be good allies here and the GOP needs them) and no more birthright citizenship. If your parents are illegal, you’re an illegal and you never can get citizenship.
Those three solve most of the problem. Fines, taxes, etc. are already acceptable to the Dems. If you do the border legislation correctly you can make the state and the Feds jointly responsible. That will end the Federal hanky panky in immigration law. Let the border states deal with it and political needs will drive the enforcement.
How very odd. You insist on being "realistic" in our expectations. Yet, the above expectation is even more unlikely than mass deportation.
