Two things:
A) Boosters only go one direction, which is forward.

AFAIK Pods inherit most things from the ship. This includes: Position, orientation, spin torque (as opposed to spin speed; more on this in a sec), and speed.
Now, in order to have a useful 'eject' booster, you would have to override the orientation and zero the spin torque. Now, spin torque is important to differentiate from spin speed - Spin speed is universal; you spin something at 2 degrees per second, it doesn't matter what it is, it spins at 2 degrees per second. Spin torque, on the other hand, is the power making the spin. Something massive, like a cap ship, spinning at 2 degrees per second might involve enough torque to have the pod spin at 2
hundred degrees per second (Ever been in a BIOS pod after ejecting from a cap ship? Your thrusters are turned off when ripcording, so no spin is canceled, and it gets, well, nauseating). Now, in order to make the eject booster work, you would have to A) equip the pod with a booster,

Give the pod fuel, and C) Override the pod's initial orientation and spin.
The orientation has some issues - mainly, depending on what angle you're going at, the pod might go directly toward you or directly away from you, either of which keeps it in your guns. The most common 'facing' is either near-directly forward, which means that a forward or backward boosting pod wouldn't work. The second most common is from one of the sides, making side orientation boosts out. The best would be an up or down, but you're still going to have possiblities of shooting the pod.
As an idea, though, it's excellent. Not a perfect solution, and not high priority, but something that's more than 'ZOMG COOL!' - It also has the fact that while it doesn't solve it perfectly, it is workable
