The only problem with your plan is that Ted Cruz is unable to even come within striking distance of Trump in the polls. He’s just not going to be the nominee. In many polls Cruz is still at 7%-8.5%. A few polls at 10%-11% and I guess the one poll at 18% which is still 10pts behind Trump. Where do you see him making up 10 points? I’m not seeing it.
No other candidate in the GOP race is going to surge to overtake Trump. He’s just too far out in front.
