I doubt if it's a smart decision. Even Abeokuta to Iperu is about 55km. For scalability, I'd think the future governors should include a light rail from core axis as a complementary project to enrich the scalability of the airport, else it won't max it full potentials.
Finally, MMIA will have some rest.
