As for if Clinton and Trump were to pick each other, they must follow party rules so they can't pick each other.

Actually they can.....They would only be eligible to become president for two years in the event the sitting president either passed away or was removed from office.  Under the constitution and the 22nd amendment the maximum any person could ever serve as president would be 10 years.
