Neutral IDs are generally only granted to Angels and SRPed Camera Ships. Since that ID belongs outside of the RP environment (Doesn't exist InRp) and your character is an InRp one, I doubt there'd be any explanation you can offer on why your char would need that ID (since it technically doesn't).
Unless you're planing on using a transport larger than 3.6k of cargo on that char, Freelancer ID would be your best option, as unlike other IDs, it doesn't have any repninjas. (aside from the obvious repninjas to admins, nomads, wilde, etc.)
