Use the VFX to assign another mix to the layer.

In the alternate mix, assign 2 layers and position a Y offset to each to put them above an below the X axis respectively.

Then just set the Y rotate to spin and you have your effect.

If you make these mix assignments as presets then you can even use a DMX preset trigger with very little headache.

What's better is that you can make as many of these as you can by replicating the process.
Interested in this but not quite following your method here??
