Vehicles are very cheap compared to mechs, and in the lore they are bountiful. Many outter laying worlds may only have a few mechs to defend an entire planet. So it seems like adding vehicles and elementals could open up many new gameplay options later on.
Defending worlds: Say you faction has many poor worlds under its control. In universe, they are not going to send a huge mech armada to take such a planet when only vehicles are defending it. You could have a game mode where the opposing team is composed of only 1 or 2 mechs against the other team comprised of 12+ vehicles. The goal of the mech team is to capture the objective, while the defenders have randomly spawn in different vehicles and can keep spawning until the match is over.
Covert ops: 1 or 2 mechs vs the other team comprised of elementals. Elementals obvious having the advantage of being small and able to hide more effectively. They have to infiltrate and destroy a drop pod or factory before the mechs can hunt them down. Defenders would have to choose wisely between a fast mech able to keep up with the elementals and rush around quickly, but much more vulnerable to being destroyed; or a heavy/assault mech which can easily wipe the floor with the elementals but is vulnerable to being lured away from his defending objective.
There are a ton of different modes and gameplay styles that could be implimented to MWO that could effectively extent the life span of this game.
