Turtles and Spawners

[Torigoma]

So I have a Skeleton Spawner set up so that they drop down into a hole and I can kill thing. I've been thinking of sticking a Turtle there to do the killing for me, however, I wanted to know if there was a way to make the turtle kill them faster, like when using a Sword of the Zephyr?

Let them drop from a height close to killing them, reducing the number of necessary attacks.
If the drop spot is 2x2 wide, you can put eight turtles around, if four is not enough.
In my world, I have a double T5 blaze spawner, and eight turtles are just enough to keep them killing fast enough.

2 turtles are enough for a T5, if they only need to hit once per mob.

Knowing that, dropping mobs from 20 blocks is a great way of making the killing way faster.
