This is so patently absurd. It's going to cost way more than $400M to strip it down to its last screw (essential for security reasons) , design and retrofit with top secret communications systems, electromagnetic pulse hardening, in-flight refuelling and defence systems. To do that is going to take more than four years when A he might be dead anyway B it goes to 'his library' C he shouldn't (!) be president any more. https://www.bbc.com/news/articles/cq855lx87z3o
