I'm sure you won't get any extra attention if you show them a freshly wiped phone, totally normal. Unfortunately I think you'd have to have the phone activated with a different Apple account. But if they ask you questions (like "do you have any other icloud accounts") don't lie, it never makes it better. Just say that this is your travel account. This is now quite standard practice for execs when travelling to e.g. China.
