In my opinion, yes and no.
Yes, eccentric only training will bring the same benefits. No, in that if you can already do a regular pushup, then you will not get the full benefits that eccentric only training offers unless you add external weight for your eccentrics.
The real key to eccentric only training is to take advantage of the fact that you can handle more weight in the eccentric than you can in the concentric and getting the neural and muscular adaptations from the increased weight will carry over to the full exercise. Doing eccentrics only with the same weight (in this case bodyweight) that you are using for the full exercise is a waste IMHO.
If you want to vary your workouts, I would use some of the suggestions provided by starmac or add external resistance with bands, chains, or vests.
