Using OAR to replace one long animation with multiple shorter animations...?

[Anunya]

There's a dance mod I like - Sensual Dancer - but I'm not really fond of the (long) dance animations it comes with.

 

So I've set up OAR with a variant folder for the (long) default dance animations, and I've put a bunch of Gunslicer's animations inside.

 

What I'd like to happen is for the GS animations to randomly cycle until I do something to interrupt them.

 

What seems to happen is that one of the GS animations plays for a short while and stops.

 

Is there a way to fix that with the correct set of conditions and settings in OAR - and if so, what are they?
